Answer:
The temperature rise is 25°C
Explanation:
The heat of a substance is obtained using the equation:
Q = m*S*ΔT
Where Q is heat in kJ, m is the mass of the susbtance, S is specific heat of the material and ΔT change in temperature.
Replacing:
Q/S = m*ΔT
As Q is constant because the heat is the same and S is the specific heat of the material (Constant). We can write:
m1*ΔT1 = m2*ΔT2
Where m is mass and ΔT change in temperature of 1, initial conditions of the substance and 2, final conditions of the substance.
Replacing:
m1 = 10kg
ΔT1 = 55°C
m2 = 22kg
ΔT2 = ?
10kg*55°C = 22kg*ΔT2
ΔT2 = 25°C
