Answer:
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
