Question

The specific heat of a substance is the amount of heat required to change the temperature of a given mass amount of heat energy that is stored in chemical bonds amount of potential energy in a material that is released when a substance undergoes combustion and gives off heat temperature at which a compound starts to melt temperature at which a given mass's heat increases Given the following specific heats and that each sample had the same mass, which of the following materials would cool the slowest? ammonia, 4.70 J/(g degree C) aluminum, 0.90 J/(g degree C) All cool at the same rate. water, 4.184 J/(g degree C) silver, 0.24 J/(g degree C)

Explanation / Answer

23) The expression for specific heat is,

Q = mC delta T

C = Q/m delta T

So, this is equal to amount of heat required to change temperature of given mass

option (A)

(24)

The lower the secific heats, the lower will be the heat required and the faster will be the temperature change.

So, the answer is (D) silver 0.24 J/g oC
