Definition and Examples of Bad News Messages

Definition and Examples of Bad News Messages In business writing, a bad-news message is a letter, memo, or email that conveys negative or unpleasant information- information that is likely to disappoint, upset, or even anger a reader. It is also called an  indirect message or a negative message. Bad-news messages include rejections (in response to job applications, promotion requests, and the like), negative evaluations, and announcements of policy changes that dont benefit the reader. A bad-news message conventionally begins with a neutral or positive buffer statement before introducing the negative or unpleasant information. This approach is called the indirect plan. Examples and Observations It is much, much worse to receive bad news through the written word than by somebody simply telling you, and I’m sure you understand why. When somebody simply tells you bad news, you hear it once, and that’s the end of it. But when bad news is written down, whether in a letter or a newspaper or on your arm in felt tip pen, each time you read it, you feel as if you are receiving the bad news again and again. (Lemony Snicket, Horseradish: Bitter Truths You Cant Avoid. HarperCollins, 2007) Sample: Rejection of a Grant Application On behalf of the members of the Research Scholarship Committee, thank you for submitting an application for this years Research Scholarship grants competition. I’m sorry to report that your grant proposal was among those that were not approved for funding in the spring. With the reduction in grant funds caused by budget cuts and the record number of applications, I’m afraid that many worthwhile proposals could not be supported. Although you did not receive a grant this year, I trust that you will continue to pursue both internal and external funding opportunities. Introductory Paragraph The introductory paragraph in the bad-news message should accomplish the following objectives: (1) provide a buffer to cushion the bad news that will follow, (2) let the receiver know what the message is about without stating the obvious, and (3) serve as a transition into the discussion of reasons without revealing the bad news or leading the receiver to expect good news. If these objectives can be accomplished in one sentence, that sentence can be the first paragraph. (Carol M. Lehman and Debbie D Dufrene, Business Communication, 15th ed. Thomson, 2008) Body Paragraph(s) Deliver the bad news in the body of the message. State it clearly and concisely, and explain the reasons briefly and unemotionally. Avoid apologies; they weaken your explanation or position. Try to embed the bad news in a supporting, not the topical, sentence of a paragraph. Furthermore, try to embed it in a subordinate clause of a sentence. The purpose is not to conceal the bad news, but to soften its impact. (Stuart Carl Smith and Philip K. Piele, School Leadership: Handbook for Excellence in Student Learning. Corwin Press, 2006) Closing The closing of a message containing negative news should be courteous and helpful. The purpose of the closing is to maintain or rebuild goodwill. ... The closing should have a sincere tone. Avoid overused closings such as If you have any questions, please dont hesitate to call. ... Offer the receiver another option. ... Presenting another option shifts the emphasis from the negative news to a positive solution. (Thomas L. Means, Business Communications, 2nd ed. South-Western Educational, 2009)

Calculate Energy Required to Turn Ice Into Steam

Calculate Energy Required to Turn Ice Into Steam This worked example problem demonstrates how to calculate the energy required to raise the temperature of a sample that includes changes in phase. This problem finds the energy required to turn cold ice into hot steam. Ice to Steam Energy Problem What is the heat in Joules required to convert 25 grams of -10  °C ice into 150  °C steam?Useful information:heat of fusion of water 334 J/gheat of vaporization of water 2257 J/gspecific heat of ice 2.09 J/g ·Ã‚ °Cspecific heat of water 4.18 J/g ·Ã‚ °Cspecific heat of steam 2.09 J/g ·Ã‚ °CSolution:The total energy required is the sum of the energy to heat the -10  °C ice to 0  °C ice, melting the 0  °C ice into 0  °C water, heating the water to 100  °C, converting 100  °C water to 100  °C steam and heating the steam to 150  °C. To get the final value, first calculate the individual energy values and then add them up.Step 1: Heat required to raise the temperature of ice from -10  °C to 0  °C Use the formulaq mcΔTwhereq heat energym massc specific heatΔT change in temperatureq (25 g)x(2.09 J/g ·Ã‚ °C)[(0  °C - -10  °C)]q (25 g)x(2.09 J/g ·Ã‚ °C)x(10  °C)q 522.5 JHeat required to raise the temperature of ice from -10  °C to 0  °C 522.5 JStep 2: Heat required to convert 0  °C ice to 0  °C waterUse the formula for heat:q m ·ÃŽâ€Hfwhereq heat energym massΔHf heat of fusionq (25 g)x(334 J/g)q 8350 JHeat required to convert 0  °C ice to 0  °C water 8350 JStep 3: Heat required to raise the temperature of 0  °C water to 100  °C waterq mcΔTq (25 g)x(4.18 J/g ·Ã‚ °C)[(100  °C - 0  °C)]q (25 g)x(4.18 J/g ·Ã‚ °C)x(100  °C)q 10450 JHeat required to raise the temperature of 0  °C water to 100  °C water 10450 JStep 4: Heat required to convert 100  °C water to 100  °C steamq m ·ÃŽâ€Hvwhereq heat energym massΔHv heat of vaporizationq (25 g)x(2257 J/g)q 56425 JHeat required to convert 100  °C water to 100  °C steam 56425Step 5: Heat required to convert 100  °C steam to 150  °C steamq mcΔTq (25 g)x(2.09 J/g ·Ã‚ °C)[(150  °C - 100  °C)]q (25 g)x(2.09 J/g ·Ã‚ °C)x(50  °C)q 2612.5 JHeat required to convert 100  °C steam to 150  °C steam 2612.5Step 6: Find total heat energyHeatTotal HeatStep 1 HeatStep 2 HeatStep 3 HeatStep 4 HeatStep 5HeatTotal 522.5 J 8350 J 10450 J 56425 J 2612.5 JHeatTotal 78360 JAnswer:The heat required to convert 25 grams of -10  °C ice into 150  °C steam is 78360 J or 78.36 kJ.
