Question

A heavy copper pot of mass 2000g ( including the cooper lid) is at temperature of 150°C . 100g of water at 25°C is poured into the pot and the lid of the pot is quickly closed so that no steam can escape. Find the final temperature of the pot and its content. [ specific heat capacity of pot is 0.104 calories/ gram Celsius]​

Answer 1

A hot copper pot of mass 2.0 kg (including its copper lid) is at a temperature of 150 °C. You pour 0.10 kg of cool water at 25°C into the pot, then quickly replace the lid so no steam can escape. Find the final temperature of the pot and its contents, and determine the phase of the water (liquid, gas, or a mixture). Assume that no heat is lost to the surroundings.
