# Temperature Formula

Temperature Formula

Temperature is a magnitude referred to a body's common notions of measurable heat. It is measured on the scales of Celsius, Fahrenheit and Kelvin. The temperature change depends on the amount of heat released or absorbed.

Temperature difference = amount of heat absorbed or released/ mass of the body* specific heat of the body.

The equation is written

ΔT = Q/m*c.

ΔT: Temperature difference.

Q: Amount of heat absorbed or released

m: mass of the body

c: specific heat of the body

Temperature Questions:

1) Calculate the temperature if 160 J of heat is released by the body of mass 10 Kg having specific heat of 0.5 J/KgoC.

Answer: First calculate the dynamic viscosity using the formula above, where Q = 160J, m = 10kg and c = 0.5J/kgoC.

ΔT = Q/m*c

ΔT = 160J/10kg*0.5 J/kgoC

ΔT = 32oC.

2) Calculate the heat released when the temperature changes by 60oC by a body of mass 8 Kg having specific heat of 0.04 J/kg oC.

Answer: To calculate the heat released, we will use the above equation clearing Q, where ΔT = 60oC, m = 8kg and c = 0.04 J/kgoC.

ΔT = Q/m*c

Q = ΔT*m*c

Q = 60 oC*8kg*0.04 J/kgoC

Q = 19.2J.
