J of energy is needed to heat 1 kg of water by , but only 140 J is needed to heat 1 kg of mercury by . Which material has the higher specific heat capacity?
A block of steel and a block of asphalt concrete are left in direct sunlight. Assuming that both materials start at and both absorb energy from sunlight equally well, determine which material will reach a temperature of first. Use a value of for the specific heat capacity of steel and use a value of for the specific heat capacity of asphalt.
