state gov RPSC 2nd Grade Senior Teacher Mock Test Series 2025 Physics Thermal Properties of Matter Thermal expansion
How much thermal energy is required to change a 40 g ice cube from solid at - 10°C to steam at 110°C.
[Assume latent heat of fusion for water = 80 kcal/kg.
specific heat of water = 1 k cal/kg °C,
specific heat of Ice = 0.5 kcal kg °C,
specific heat of steam = 0.48 kcal /kg °C,
latent heat of vaporisation of water = 540 kcal/kg ]
