Question

Calculate the amount of heat required (in kJ) to raise the temperature of $40 k g$ of compound from $10^{\circ} C$ to $35^{\circ} C$ . Specific heat capacity of the compound is $50 J / k g^{\circ} C$ .

Open in App

Solution

Given:
Change in temperature,
$Δ T = 35 - 10$
$Δ T = 25^{\circ} C$
Mass of a compound, $m = 40 k g$
Specific heat capacity, $c = 50 J / k g^{\circ} C$

$Q = m c Δ T$
$Q = 40 \times 50 \times 25$
$Q = 50, 000 J = 50 k J$
