A solid sphere and a hollow sphere of the same material and size are heated to the same temperature and allowed to cool in the same surroundings. If the temperature difference between the surroundings and each sphere is T, then :

A solid cube and a solid sphere of the same material have equal surface area. Both are at the same temperature 120^(@)C , then

Assertion : A solid sphere and a hollow sphere of same material and same radius are kept at same temperature in atmosphere. Rate of cooling of hollow sphere will be more. Reason : If all other conditions are same, then rate of cooling is inversely proportional to the mass of body.

Assertion : A solid sphere of copper of radius R and a hollow sphere of the same material of inner radius r and outer radius R are heated to the same temperature and allowed to cool in the same environment. The hollow sphere cools faster. Reason : Rate of cooling is according to Stefan's law which is E alpha T^(4)

A solid sphere of copper of radius R and a hollow sphere of the same materail of inner radius r and outer radius A are heated to the same temperature and allowed to cool in the same environment. Which of tehm starts cooling faster?

Assertion : A solid and hollow sphere of same diameter and same material when heated through the same temperature will expand by the same amount. Reason : The change in volume us independent of the original mass but depends on original volume.
