ICSE Class 10 Physics 2022 Solved Paper

Question : 15

Total: 45

Calculate the thermal capacity of 40g of water.
[Specific heat capacity of water =4200 Jkg−1‌∘C−1]

Solution:

Given : m=40g=‌

1000

=0.04‌kg
C=4200Jkg−1‌∘C−1
Thermal capacity (C′)
‌=mass(m)×‌ Specific heat capacity ‌(C)
‌=0.04×4200
‌=168J∘C−1
