Question

If the pot contains 375g of water, use the equation Q=mcAT to calculate how much heat is needed to raise its temperature by 25°C. The specific heat of water is 4.18 J/gºC.​

Answer 1

To raise the temperature of 375g of water by 25°C, one would need 39337.5 joules of heat energy, calculated using the specific heat capacity of water and the formula Q = mcΔT.

Step-by-step explanation:

To calculate the amount of heat needed to raise the temperature of 375g of water by 25°C, you can use the equation Q = mcΔT, where Q is the heat energy in joules, m is the mass in grams, c is the specific heat capacity in J/g°C, and ΔT is the change in temperature.

Given that the specific heat capacity of water is 4.18 J/g°C, the calculation would be as follows:

Q = 375g * 4.18 J/g°C * 25°C
Q = 375g * 4.18 J/g°C * 25
Q = 39337.5 J

Therefore, the heat needed to raise the temperature of 375g of water by 25°C is 39337.5 joules.
