If temperature scale is changed from `'^(@)C` to `'^(@)F`, the numerical value of specific heat

A

increase

B

decrease

C

remain same

D

nothing can be decided

Text Solution

Verified by Experts

The correct Answer is:
B

Since magnitude of `1^@ `F is equal to` 5/9 ` of magnitude of `1^@`C, the numerical value of specific heat will decrease.

How much heat (in joule) is required to raise the temperature of 205 g of water from 21.2^(@)C to 91.4^(@)C . Specific heate of water is 4.18 J g^(-1) .^(@)C^(-1) Strategy : The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1^(@C . Thus Specific heat = (("Amount of heat in joules"))/(("Mass of substance in grams")("Temperature change in" .^(@)C)) Rearrangement gives. Amount of heat (q) = Mass of substance (m) xx Specific heat (c ) xx Temperature change (Delta T)
