Question 3
In past times, when there was no electricity, on a cold winter night, people used to bring a hot object to bed.

Characteristics of Two Objects |

|
Mass (Kg) |
Temperature (°C) |
Specific Heat (J/g °C) |

|
Object A Solid |
10 |
100 |
0.450 |
|
Object B Liquid in container |
10 |
100 |
4.184 |
Based on the data, which hot object do you predict could keep you warmer throughout the night and why?
|
A |
Object A will cool off slowly because it is a solid with low specific heat and will keep me warm all night. |
|
|
B |
Object B will take more time to release heat because it has absorbed more heat, so it will keep me warm all night. |
|
|
C |
Object B will cool off too fast because it is a liquid with high specific heat, so it will make me feel cold in the middle of the night. |
|
|
D |
Either object A or B will release the same amount of heat because they are at the same temperature and will keep me warm all night. |
