Temperature
Temperature is the measurement of total kinetic energy in a space. True or false?
False, it is the Average Kinetic Energy
Describe the flow of heat.
Heat flows from high temperature to lower temperatures.
If a person is moving an object is there energy transfer?
Yes
Define dependent and independent variables
Dependent variables are what we are measuring. Independent variables are what we change in our experiment.
What factors could we use to compare the thermal energy of two objects?
Mass, state of matter, composition, and temperature.
If an object is designed to keep a constant temperature is its aim to maximize or minimize thermal energy transfer?
Minimize thermal energy transfer
the transfer of energy that occurs when a force moves an object over a distance.
Which type of heat transfer does not require contact or a medium?
Radiation
If a bowling ball is dropped in a pool and makes a big splash how could we describe the transfer of energy?
The kinetic energy of the bowling ball gets transferred to the pool water.
Define criteria and constraints
Criteria are things we want our solution to have. Constraints are limitations we cannot break when designing a solution.
What is measured in joules, depends on an object's mass, temperature change, and specific heat capacity?
Thermal energy
How can we measure how good something is at thermal conductivity?
We can measure and compare the time it takes for thermal energy to be transferred to another object.
Explain the transformation of thermal energy into kinetic energy when we stand next to a heater.
The heater gives off thermal energy. Our skin absorbs that energy. Our body particles begin to move faster. The thermal energy turned into kinetic energy.
Why is the temperature higher in cities than in farmlands?
Asphalt from the streets absorbs thermal energy more than grass.
How is mass related to thermal energy? Why?
The more mass in a space the higher the thermal energy in that space because more mass means more particles which means more total thermal energy.
A metal spoon is placed in a bowl of hot soup. The handle becomes too hot to touch, even though it is not in the soup. Does the spoon transfer energy to the soup? Explain
No because the spoon was at a lower temperature so no thermal energy would go from the spoon to the soup.
