Thermodynamics (No Entropy) Ch Review

If two objects have different temperatures when they come in contact, heat will flow from the warmer object to the cooler one UNTIL ____________

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy

For a skillet, used for cooking, do you want a high or low specific heat

• High, so that it will need more energy to heat up

• Low, so that it will change temperature quickly

In an exothermic process, the surroundings are gaining energy.

• True
• False

Calorimeters use insulating materials to:

• encourage affordable materials in science experiments in schools.
• preserve the heat of the environment outside the Styrofoam cup.
• prevent heat from escaping to the environment.
• keep the liquid inside the Styrofoam cup from overheating.

A metal cube at temperature of 70°C is immersed in water at temperature of 20°C. The metal _______ heat while the water __________ heat.

• gains, loses

• loses, gains

What is a substance that does NOT conduct heat well?

• Conductor
• Insulator
• Convector
• Radiator

What is a substance that DOES conduct heat well?

• Conductor
• Insulator
• Convector
• Radiator

Why does an ice cube melt when dropped into hot liquid?

• The liquid absorbs heat from the ice.

• Heat from the liquid transfers to the ice.

• Heat from the ice transfers to the liquid.

• Cold from the ice transfers into the liquid.

Heat is measured in 

• joules
• grams
• degrees celcius

Heat transfer by conduction occurs when...

• particles bump into each other
• large numbers of atoms move from place to place
• atoms give off heat in the form of electromagnetic waves
• electromagnetic waves travel from place to place through a vacuum
