Answer 1

Q=c*m(t1-t2)
Q= количество теплоты 
c=удельная теплоёмкость
m=масса
t1=начальная температура
t2=конечная температура

Answer 2

Calculation of Heat Quantity during Heating

To calculate the quantity of heat generated during heating, you can use the formula:

Q = mcΔt

Where: - Q is the quantity of heat (in joules) - m is the mass of the substance being heated (in kilograms) - c is the specific heat capacity of the substance (in joules per kilogram per degree Celsius) - Δt is the change in temperature (in degrees Celsius)

Let's consider an example to illustrate the calculation.

Suppose we have a substance with a mass of 4 kilograms, a specific heat capacity of 400 joules per kilogram per degree Celsius, and we want to heat it from 20 degrees Celsius to 120 degrees Celsius.

Using the formula, we can calculate the quantity of heat as follows:

Q = mcΔt Q = 400 * 4 * (120 - 20) Q = 400 * 4 * 100 Q = 160,000 joules

Therefore, the quantity of heat generated during the heating process is 160,000 joules.

Please note that this calculation assumes that there are no phase changes (such as melting or boiling) occurring during the heating process.

I hope this helps! Let me know if you have any further questions.
