what does Q=m times t times c. mean

and wat are the meaning of each letter

The equation Q = m * t * c represents a mathematical relationship between three variables: Q, m, t, and c.

Q represents the quantity of heat energy transferred. It is measured in joules (J) or calories (cal).

m represents the mass of the object or substance involved. Its unit can be kilograms (kg) or grams (g).

t represents the change in temperature. It is usually measured in degrees Celsius (°C) or Kelvin (K).

c represents the specific heat capacity of the substance. It is a measure of how much heat energy is required to raise the temperature of a given mass of the substance by 1 degree Celsius. The unit for specific heat capacity is usually in joules per gram per degree Celsius (J/g°C) or calories per gram per degree Celsius (cal/g°C).

So, when you multiply the mass (m), change in temperature (t), and specific heat capacity (c) together, you get the quantity of heat energy (Q) transferred. This equation allows you to calculate the amount of heat energy gained or lost by an object or substance during a change in temperature.
