To calculate the heat required to raise the temperature of a mass, we use the formula for heat transfer:

$Q = mc\Delta T$

Where:

• $Q$ is the heat energy (in joules, J),
• $m$ is the mass (in kilograms, kg),
• $c$ is the specific heat capacity (in joules per kilogram per degree Celsius, J/kg°C),
• $\Delta T$ is the change in temperature (in degrees Celsius, °C).

Given:

• Mass, $m = 1.5 \, \text{kg}$,
• Temperature change, $\Delta T = 120^\circ \text{C}$,
• Specific heat capacity, $c$ (value not provided, but can be entered).

To complete the calculation, we need the value of the specific heat capacity $c$. If you provide that, I can calculate the heat required.

Would you like to provide the specific heat, or should I assume a common value for a particular material?

Relative Questions:

1. What is the material of the object you're referring to (so we can determine the specific heat)?
2. How does the specific heat capacity vary with different materials?
3. What are some common applications of heat transfer calculations in engineering?
4. How does heat transfer differ in different phases of matter (solid, liquid, gas)?
5. What is the significance of using correct units in heat transfer calculations?

Tip: For water, the specific heat capacity is commonly $4,186 \, \text{J/kg°C}$, one of the highest values among substances.
