The specific beta in aluminum is 0,900 J/g • Celsius. How much heat is required to raise the temperature of a 30.0 g block of aluminum from 25 degrees celsius to 75 degrees celsius

1350J

Explanation:

Heat energy = ?

Mass = 30.0g

Specific heat capacity (c) = 0.90J/g°C

Initial temperature (T1) = 25°C

Final temperature (T2) = 75°C

Heat energy (Q) = mc∇T

Q = heat energy

M = mass of the substance

C = specific heat capacity of the substance

∇T = change in temperature of the substance = T2 - T1

Q = mc∇T

Q = 30 * 0.90 * (75 - 25)

Q = 27 * 50

Q = 1350J

The heat energy required to raise the temperature of the metal from 25°C to 75°C is 1350J
