Enter the power in watts, mass in kilograms, specific heat in J/kg°C, and time in seconds into the calculator to determine the temperature change in degrees Celsius. This calculator helps in understanding how much energy is required to change the temperature of a given mass.
Watts to Temperature Change Formula
The following formula is used to calculate the temperature change.
ΔT = (P * t) / (m * c)
Variables:
- ΔT is the temperature change (°C)
- P is the power in watts (W)
- t is the time in seconds (s)
- m is the mass in kilograms (kg)
- c is the specific heat capacity (J/kg°C)
To calculate the temperature change, multiply the power by the time and divide the result by the product of the mass and the specific heat capacity.
What is Temperature Change?
Temperature change refers to the variation in temperature that a substance undergoes when energy is added or removed. In the context of this calculator, it is the change in temperature of a mass when a certain amount of energy, measured in watts, is applied over a period of time. The specific heat capacity of the material is a crucial factor in determining how much the temperature will change for a given amount of energy.
How to Calculate Temperature Change?
The following steps outline how to calculate the temperature change.
- First, determine the power in watts (P).
- Next, determine the mass in kilograms (m).
- Next, determine the specific heat capacity (c) in J/kg°C.
- Next, determine the time in seconds (t).
- Next, gather the formula from above = ΔT = (P * t) / (m * c).
- Finally, calculate the temperature change (ΔT) in degrees Celsius.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Power (P) = 500 watts
Mass (m) = 2 kilograms
Specific Heat (c) = 4186 J/kg°C (specific heat of water)
Time (t) = 3600 seconds (1 hour)
