A cooking smoker, used to cook meats, works by allowing the warm air filled with smoke to rise to the meat, while the cooler air sinks closer to the fire. What type of heat transfer is responsible for smoking the meat?
Electrical
Radiation
Convection
Conduction
A student was conducting an experiment in which a heater was placed on one side of a large box and a thermometer on the other side. The student removed all the air from the box, turned on the heater, and recorded the change in temperature. What was the student's model designed to show?
the transfer of heat through convection
the transfer of heat through electricity
the transfer of heat through radiation
the transfer of heat through conduction
This appliance dries clothes primarily by converting —
electrical energy to heat and mechanical energy
mechanical energy to heat and electrical energy
electrical energy to heat and light
mechanical energy to heat and vaporization
A teacher rubbed a match against a piece of sandpaper. The match started to burn. Which statement best describes the energy changes that occurred?
The chemical energy stored in the match changed to thermal energy and light energy.
The thermal energy stored in the match changed to light energy and chemical energy.
The light energy and thermal energy stored in the match changed to mechanical energy.
The light energy and thermal energy stored in the match changed to chemical energy.
What transfer of heat is responsible for cooking the chicken?
radiation
convection
electrical
conduction
When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water. What two kinds of heat transfer are represented?
Stove → Pot = radiation, Pot → Egg = conduction
Stove → Pot = conduction, Pot → Egg = radiation
Stove → Pot = convection, Pot → Egg = conduction
Stove → Pot = conduction, Pot → Egg = convection
Which of these actions, on their own, will cause ice to change to water? Remember, hot --- > cold
removing heat from the ice
adding sand to the ice
crushing the ice
adding heat to the ice

What energy transformation occurs in the chameleon as it quickly launches its tongue to catch an insect?
Radiant --> Chemical
Thermal --> Chemical
Chemical --> Mechanical
Mechanical --> Chemical
What energy transformation occurs as howler monkeys loudly call to each other in the forest?
Chemical --> Mechanical --> Sound
Chemical --> Sound --> Thermal
Sound --> Chemical --> Radiant
Mechanical --> Chemical --> Sound
What energy transformation occurs as as an elephant walks through the savanna?
Thermal --> Chemical + Mechanical
Mechanical --> Chemical + Thermal
Radiant --> Chemical + Mechanical
Chemical --> Mechanical + Thermal
When is your answer negative?
When the sample is cooled or loses heat energy.
When the sample heats up or gains heat energy.

The graph shows the cooling curve of a substance. At which stages the specific latent heat released?
AB and CD
BC and DE
AB and EF
BC and CD
From point A to point E, the sample is going through an
exothermic process by releasing heat to the surroundings
exothermic process by absorbing heat from the surroundings
endothermic process by releasing heat to the surroundings
endothermic process by absorbing heat from the surroundings
Which of the following best describes the energy transformations that occur when a flashlight that runs on batteries is turned on?
