Row 1, Col 1 What is the difference between Heat + temperature? Heat is the transfer of energy between objects at different temperatures which causes temperatures of both objects to change

1,2 What is convection + give an Example of convection ? Convection is the transfer of energy as heat by the movement of liquid or gas / ex. in a room it is warmer near the ceiling than near the floor

1,3 What is conduction + give an Example of conduction? Conduction takes place when energy is transferred from one particle to another without the movement of matter. / ex when you hold a pot of boiling water over a fire and the metal handle becomes hot.

1,4 What two units are used to measure heat? The Calorie and the joule.

1,5 What is thermal energy? Thermal energy is the total kinetic energy of all particles in a substance.

2,1 Why would one substance have more thermal energy if two substances are at the same temperature? - One substance would have more thermal energy than another even if they were at the same temperature because it must be larger and contain more particles.

2,2 What is the relationship between calories and temperature? 1 calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius; therefore, 100 calories are needed to raise the temperature of 10 grams of water by 10 degrees Celsius.

2,3 What is an insulator? An insulator is a material that is a poor conductor of heat./

2,4 What is the kinetic theory of matter?. The kinetic theory of matter states that all of the particles that make up matter are constantly in motion.

2,5 Give an example of a tool used to measure temperature. -A thermometer is used to measure temperature.

3,1 What is the freezing/melting point of water in Celsius and what is the boiling point of water in Celsius? - The freezing/melting point of water is 0 °C and the boiling point of water is 100 °C.

3,2 What is the relationship between temperature and movement of particles? - The warmer the temperature, the quicker the particles move. The cooler the temperature, the slower the particles move.

3,3 What is the freezing point of water on the Kelvin scale? The freezing point of water is 273 K.

3,4 What is potential energy? - Potential energy is the energy stored due to an object’s position, condition, or chemical composition.

3,5 What is the law of conservation of energy? -The sum of all energy does not change; instead it can be converted into other forms.

4,1 What type of energy is stored in a battery? Chemical energy.

4,2 What is gravitational potential energy? -Potential energy is the energy that an object has due to position, condition, or chemical composition. -Gravitational potential energy increases as the object’s height increases.

4,3 If cars are moving at the same speed what can give one car more kinetic energy than the other? -The mass of the car. The object with the greatest mass has the greatest kinetic energy when the objects are moving at the same speed.

4,4 Define radiation and give an example of a practical use of radiation. Radiation is the transfer of energy by electromagnetic waves. An example is a solar cooker.

4,5 Chemical- is a form of potential energy. It depends on the kind of atoms and their arrangements. Food is an example of chemical energy. Define chemical energy

5,1 Define kinetic energy Kinetic- is the energy of an object that is in motion.

5,2 Define electromagnetic energy Electromagnetic- is energy transmitted through space in the form of electromagnetic waves.

5,3 Define electrical energy Electrical- is the energy that results from the position or motion of charges particles.

5,4 Give an example of potential energy. -An example is a slingshot.

5,5 Give an example of an insulator Ex. Plastic is an insulator, or a poor conductor of energy as heat
