Question

Which would take a longer time to warm up, a piece of brass or a piece of marble, given that both

have the same mass? Explain your answer.

Answer 1

Step-by-step explanation:

specific heat of marble is 880 J/kg °C

specific heat of brass is 920 J/kg °C

If Q heat is given to a body of mass m and specific heat s , and there is a rise of temperature t

Q = m s t

t = Q / m s

if Q and m is constant

t is inversely proportional to specific heat .

so rise in temperature will be inversely proportional to specific heat .

lower the specific heat , higher will be the rise in temperature . Since marble has lower specific heat , rise in temperature in marble will be higher and quicker .

So brass will take longer time to warm up.
