Question

how many joules of heat are needed to raise the temperature of 10.0 g of aluminum from 22 degrees celcius to 55 degrees celcius, if the specific heat of aluminum is 0.90 joules

Answer 1

Q = m*c*∆T
Where, Q is the heat, m is the mass, c is the specific heat and ∆T is the variation of temperature (in Kelvin or ºC).

\[Q=m*c*\Delta T\]\[Q=(10.0g)*(0.90\frac{J}{g*C})*(55C-22C)\]\[Q=297J\]

Answer 2

= 297 J
if the specific heat is given in J/degree celsius/g
