One calorie is defined to be the amount of heat required to raise the temperature of 1 g of water from 14.5 C to 15.5 C. It is necessary to specify the temperature interval. Explain with the help of a graph.

ᴀɴsᴡᴇʀ:

Thus the “15° calorie” (also called the gram-calorie, or small calorie) was defined as the amount of heat that will raise the temperature of 1 gram of water from 14.5° to 15.5° C—equal to 4.1855 joules.

1. Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don't just give up

- Stephen Hawking

2. One calorie

was earlier defined to be the amount of heat

required to raise the temperature of 1g of water

by 1°C. With more precise measurements, it was

found that the specific heat of water varies

slightly with temperature. Figure 12.5 shows

this variation in the temperature range 0 to

100 °C
