how many joules would it be if you heated up a substance 14.7 degree celsius to 90 celsius at 25 grams



To calculate the amount of energy required to heat a substance, we use the specific heat formula:

\[
Q = mc\Delta T
\]

Where:
- \( Q \) is the heat energy in joules,
- \( m \) is the mass of the substance in grams (25 grams in this case),
- \( c \) is the specific heat capacity of the substance (in joules per gram per degree Celsius, \( J/g°C \)),
- \( \Delta T \) is the change in temperature (in °C), which is the final temperature minus the initial temperature.

Given:
- Initial temperature = 14.7°C
- Final temperature = 90°C
- Mass = 25 g
- Change in temperature \( \Delta T = 90°C - 14.7°C = 75.3°C \)

However, we need the specific heat capacity \( c \) of the substance to proceed. Do you know the specific heat capacity of the substance? For example:
- Water's specific heat capacity is \( 4.18 \, J/g°C \),
- Aluminum's specific heat capacity is \( 0.897 \, J/g°C \), and so on.

Once we have \( c \), we can complete the calculation. Let me know the substance, or I can use a common one like water for demonstration.

Do you want to proceed with water, or should I wait for your answer?

Here are 5 related questions:
1. What is the specific heat capacity of the substance you are working with?
2. How does the specific heat of a material affect how much energy is required to heat it?
3. How does this formula change when the substance undergoes a phase change?
4. How would the calculation differ if the mass of the substance increased?
5. What units must the temperature and mass be in for the formula to work correctly?

**Tip:** The higher the specific heat capacity, the more energy is required to heat the substance.
