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
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.
