QUIZ 2 of Temperature

Heat flows from region of ................temperature to region of..................................temperature

• lower - higher

• higher-lower

• cold-hot

• hot-cold

Give examples some physical properties that vary with temperature

• density of liquid

• volume of a gas ( at a constant pressure)

• the resistance of an electrical conductor

• kinetic energy of molecules

how do you convert celsius to kelvin?

• substract 273.15

• divide 273.15

• add 273.15

• times 273.15

What is the absolute scale of temperature?

• Celsius

• reamur

• Fahreinheit

• Kelvin

Why is the absolute scale used?

• it doesn`t arbitrarily depend on the properties of given substance

• the absolute zero means no internal energy of particles

• it depends on melting and boiling point

• it depends on the voltage
