Question

A 2 kg object has a specific heat capacity of 1,700 J/(kg \cdot⋅oC)

Answer 1

The amount of heat needed to raise the temperature of a 2kg object from 15°C to 25°C is 34000J.

HOW TO CALCULATE SPECIFIC HEAT CAPACITY:

• The amount of heat absorbed by an object can be calculated by using the following expression:

• Q = m.c.∆T

Where;

1. Q = amount of heat absorbed or released (J)
2. m = mass of object
3. c = specific heat capacity (J/g°C)
4. ∆T = change in temperature (°C)

• According to this question, 2 kg object has a specific heat capacity of 1,700J/kg°C and was raised from a temperature of 15 Celsius to 25 Celsius. The heat absorbed is calculated as follows:

• Q = 2 × 1700 × {25 - 15}

• Q = 3400 × 10

• Q = 34000J

• Therefore, the amount of heat needed to raise the temperature of a 2kg object from 15°C to 25°C is 34000J.
