Question

MATERIAL SPECIFIC HEAT

water (pure) 4,184
aluminum 900
steel 470
silver 235
oil 1,900
concrete 880
glass 800
gold 129
wood 2,500

A 0.8-kilogram piece of aluminum increases its temperature 15°C when heat is added. How much heat energy produced this change in tempurature?

A) 12 Joules
B) 900 Joules
C) 5,600 Joules
D) 10,800 Joules​

Answer 1

To calculate the heat energy produced, we can use the formula:

Q = m * c * ΔT

where Q is the heat energy produced, m is the mass of the object, c is the specific heat of the material, and ΔT is the change in temperature.

Substituting the given values, we get:

Q = (0.8 kg) * (900 J/kg°C) * (15°C)
Q = 10,800 J

Therefore, the amount of heat energy produced is 10,800 Joules. The answer is (D).
