WorksheetsTHERMAL ENERGY AND HEAT TRANSFER
Total questions: 18
Worksheet time: 13mins
The direction of energy is always from a warmer object to a relatively cooler object.
TRUE
FALSE
It is the average kinetic energy present in a system. It is the total energy of atoms in the body
Thermal energy
Heat
A cold object contains high amounts of thermal energy. When this thermal energy is transferred to a cold object, the energy is now called heat.
TRUE
FALSE
Solids, liquids, and gases become warm because of the increase in energy of their atoms or molecules.
TRUE
FALSE
It is the hotness or coldness of an object.
Heat
Temperature
The first thermometer that was developed by Galileo Galilei in 1602. It was composed of a sealed glass tube with water
Thermal meter
Digital thermometer
A device or instrument used to measure the temperature of an object.
Thermometer
Microscope
He wanted to establish a temperature scale based on three fixed points, which are (1) the freezing point of water, (2) the normal human body temperature, and (3) the coldest possible temperature
Daniel Fahrenheit
Anders Celsius
He assigned 100ºC as the freezing point of and 0ºC as its boiling point. The reversal of measurements was made by Carolus Linnaeus
Daniel Fahrenheit
Anders Celsius
He defined absolute temperature as the temperature wherein at 0º, molecules stop moving. An absolute temperature is defined as -273ºC or 0 K.
Anders Celsius
Lord Kelvin/William Thomson
The process by which heat occurs through a medium from one point to another. It is the heat transfer in solids
Conduction
Convection
A. Conductors are materials that are allow heat and electricity to pass through objects.
B. Insulators are materials that are poor conductors of heat and electricity.
Statement A is TRUE and Statement B is FALSE.
Statement A is FALSE and Statement B is TRUE.
Both statements are TRUE.
Both statements are FALSE.
The process wherein thermal energy is transmitted from one material to another by the movement of heated particles of a fluid (i.e., liquid or gas). It is the heat transfer in liquid and gas.
Conduction
Convection
The particles of liquids and gases move faster than those of solids.
TRUE
FALSE
Cold air is denser than warm air. Therefore, cold air sinks while warm air rises. When your air-conditioning unit is positioned near the ceiling, more cold air can be warmed.
TRUE
FALSE
It is the transfer of thermal energy by electromagnetic (EM) waves. It is the means by which energy from the sun reaches people on Earth
Convection
Radiation
A. White is a poor reflector but a good absorber of heat.
B. Black is a good reflector but a poor absorber of heat
Statement A is TRUE and Statement B is FALSE.
Statement A is FALSE and Statement B is TRUE.
Both statements are TRUE.
Both statements are FALSE
Give one example of conduction, one example of convection and one example of radiation. Type your answer below.
