For water, 1 calorie of heat is needed to raise 1 gram of water by 1°C, so its specific heat cw = 1 cal/g°C. The specific heat of aluminum is cAl = 0.217 cal/g°C, iron has cFe = 0.113 cal/g°C, lead cPb = 0.031 cal/g°C, and for brass cbr = 0.092 cal/g°C.
Does aluminum have a high specific heat?
Thus, the aluminum must require more energy to change its temperature. Therefore, aluminum has the higher specific heat.
How do you find the specific heat of a metal?
or Q =s•m•∆T, where Q is the amount of heat, s is the specific heat, m is the mass of the sample, and ∆T is the temperature change. This equation can be used to calculate the amount of heat that must be involved when the other three values are known or measured.
What is high specific heat?
A high specific heat capacity means it can hold a large amount of thermal energy in for a low mass or temperature change. It is also good at keeping in thermal energy, for example: Object: Mass = 3kg.
Which metal has highest specific heat?
The correct answer is 2, i.e. Aluminum. Thermal capacity is the amount of heat required to increase the temperature of an object by one degree. The following table provides the values of the thermal capacity of some of the metals and Aluminum. It shows that Aluminum has the highest thermal capacity.
