What is the formula for fusion?
The latent heat of fusion equation is the heat per mass of substance undergoing a phase change Lf=q/m L f = q / m where q is the flow of energy from one body to another, which is equal to the mass m of the substance that is losing or gaining heat multiplied by the change in temperature ΔT Δ T and the specific heat …
When the temperature is 20 degrees Celsius C what is it on the Fahrenheit F scale use the following formula degrees Fahrenheit 9 5 C +32?
For example, let us convert 20° Celsius to Fahrenheit: °F = 20 × (9/5) + 32 = 36 + 32 = 68°F. Therefore, 20° Celsius is equal to 68° Fahrenheit (20°C = 68°F).
How do you calculate temperature in degrees Celsius?
If you want to convert a normal human body temperature (98.6 F) to Celsius, plug the Fahrenheit temperature into the formula: C = 5/9 x (F – 32)…So you would have:
- C = 5/9 x (F – 32)
- C = 5/9 x (98.6 – 32)
- C = 5/9 x (66.6)
- C = 37 C.
