Answer 1

Answer:

The temperature range of 14.5°c to 15.5°c to the chosen while deciding the unit for heat. If we heat 1kg water is 1°C in diffrent temperature range than 14.5°c to 15.5°c, the amount of required will be slightly different.

Hope it helps uh buddy......

Answer 2

Answer:

While deciding the unit for heat (which is calorie), the temperature interval chosen is . We know that the amount of heat released or absorbed by a body is given as .

Now,

we also know that one calorie is defined as the amount of heat required to raise the temperature of of water through . Thus, for calorie of heat energy, the specific heat capacity of water should be . It is found experimentally that the specific heat capacity of water is . When the temperature range is .
