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.

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.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
