Question

If the temperature of water changes by 10 degrees Celsius on giving 300 calorie heat, what is
the mass of water?​

Answer 1

Answer:

Amount of the heat given to water due to rise in temperature can be computed easily by using the formula as follows:

Q=m×ΔT

Where m is mass of the water and

ΔT is the change in temperature. This formula is only applicable for water as Specific heat of water is s=1cal/g

0

C

Given Q = 300 cal

Change in temperature, ΔT=15

0

C

Thus,

m=

ΔT

Q

so m=

15

300

m = 20 gram.

The correct option is D.
