In each of the following pairs, determine the temperature change, and whether the temperature increased or decreased. a. 45° F to –10° F b. 35° C to 80° F c. –19° C to 49° C d. 137° C to 0° C e. 5° C to 19° F f. 68° F to 29° C
Accepted Solution
A:
These are six questions and six answers.
1) Question a.45° F to –10° F
i) Temperature change = Final temperature - Initial temperature
ii) Temperature change = -10 °F - 45°F = - 55 °F
iii) Conclusion: The temperature decreased 55°F
2) Question b. 35° C to 80° F
i) Convert 35°C to °F: 35 × 1.8 + 32 = 95°F
iii) Temperature change = final temperature - initial temperature = 80°F - 95°F = - 15°F
iv) Conclusion: The temperature decreased 15°F
3) Question c. –19° C to 49° C
i) Temperature change = final temperature - initial temperature = 49°C - (-19°C) = 49°C + 19°C = 68°C
ii) Conclusion: The temperature increased 68°C
4) Question d. 137° C to 0° C
i) Temperature change = final temperature - initial temperature = 0°C - 137°C = - 137°C
ii) Conclusion: The temperature decreased 137°C
5) Question e. 5° C to 19° F
i) Convert 5°C to °F
5 × 1.8 + 32 = 9 + 32 = 41°F
ii) Temperature change = final temperature - initial temperature = 19°F - 41°F = - 22°F
