JEE Physics Ch. 23 HEAT AND TEMPERATURE Questions

If equal and separate masses of alcohol and water are initially at the same temperature and they are heated for a short while, the alcohol will experience a higher change in temperature. What inverse relationship accounts for this behaviour? Why do we specify for a "short while"?


Since water has a higher boiling point, it will eventually experience a higher change in temperature, but initially, prior to boiling, alcohol heats up faster, even though it absorbs the same amount of heat as water. This is a result of alcohol's lower specific heat.
