Question

how much heat is required to raise the temperature of 250 g of aluminum by 10°c? the specific heat capacity of aluminium is 0.90 j/g°c 2,250 j 27.78 j 23,600 j 0.036 j rewatch

Explanation:

Step1: Recall the heat formula

The formula for heat \( Q \) is \( Q = mc\Delta T \), where \( m \) is mass, \( c \) is specific heat capacity, and \( \Delta T \) is temperature change.

Step2: Identify values

Given \( m = 250\space g \), \( c = 0.90\space J/g^\circ C \), \( \Delta T = 10^\circ C \).

Step3: Substitute into formula

\( Q = 250 \times 0.90 \times 10 \)
\( Q = 250 \times 9 \)
\( Q = 2250\space J \)

Answer:

2,250 J
