Answer 2

Calculation of Heat Energy

To calculate the amount of heat energy required to heat 300 g of oil in a 400 g aluminum frying pan by 50°C, we can use the formula:

Q = mcΔT

Where: - Q is the heat energy (in joules) - m is the mass of the substance (in grams) - c is the specific heat capacity of the substance (in J/g°C) - ΔT is the change in temperature (in °C)

In this case, we need to find the heat energy (Q) required to heat the oil, so we'll substitute the given values into the formula.

Given: - Mass of oil (m) = 300 g - Mass of aluminum frying pan (m) = 400 g - Change in temperature (ΔT) = 50°C

We need to find the specific heat capacity of oil (c) and aluminum (c) to complete the calculation. Unfortunately, the specific heat capacities of oil and aluminum are not provided in the question. Therefore, we cannot provide an accurate calculation without this information.

If you can provide the specific heat capacities of oil and aluminum, we can proceed with the calculation.
