Temperature Flashcards
Thermal energy
The energy possessed by an object due to its temperature it is transferred from a region of higher temperature to a region of lower temperature
Thermal equilibrium
When 2 substances in physical contact with each other no longer exchange any heat energy and bother reach an equal temperature
How to make thermometer
1) density of liquid
2) volume of gas at constant pressure
3) Resistance of a metal
4) emf of a thermocouple
Resistance of a metal
Thermistor gets hotter less resistance
What is a thermodynamic scale
Kelvin scale since it doesn’t depend on the property of any particular substance
Absolute zero
Lowest possible temperature
Absolute zero in kinetic terms
The temperature at which atoms and molecules in all substances have zero kinetic and potential energy
Kelvin to degrees
Add 273.15
Specific heat capacity
The amount of energy required to increase the temperature of 1 kg of substance by 1 degree
Formula for specific heat capacity
^Q=mc^t
Define latent heat capacity
Energy required to change the state of 1kg of a substance with no change in temperature
Latent heat of fusion
The energy required to convert 1kg of solid to liquid with no change in temperature
Latent heat of vaporisation
Energy required to convert 1kg of liquid to gas with no change in temperature
Specific latent heat formula
Q=Lm
