Two spheres of same size are made of the same metal but one is hollow and the other is solid. They are heated to same temperature, then
The temperature of the sun is measured with
When vapour condenses into liquid
A: At high altitude regions the cooking of food becomes difficult. B: Water boils at lower temperature when the pressure is low.
When water is heated from 0ºC to 10ºC, its volume
A metal sheet with a circular hole is heated. The hole
Food in the pressure cooker is cooked faster, as
Gases exert pressure on the walls of the container because the gas molecules
Temperature of B will be higher because, due to expansion, centre of mass of B will come down. Same heat is supplied but in B, Potential energy is decreased therefore internal energy gain will be more.
