Under Pressure
The definition of pressure is force acting against this.
What is a surface?
A phase change occurs when we go from one of these to another.
What are states of matter?
This states that energy cannot be created or destroyed.
What is the first law of thermodynamics?
The thermal energy that gets transferred is known as this.
What is heat?
Particles of gas stacked on top of each other leads to this.
What is atmospheric pressure
This is occurring when a substance changes from a liquid to a gas.
What is vaporization?
We break the world down into these in order to simplify things when we study energy.
What are systems?
The process of transferring energy through particle collisions is known as this.
What is conduction?
This unit of pressure weighs how much force is applied to a certain small area of an object's surface, and is often shortened to "PSI".
What are pounds per square inch?
The temperature where a solid changes into a liquid is known as this.
What is the melting point?
A plate of food would be this type of system.
What is open?
You place a steak onto a pan on the stove and start to cook it. In this energy transfer, the steak is this.
What is receiver?
This happens to pressure when we take away gas particles from a container.
What is decrease?
The temperature of a substance stays constant during a phase change because energy is going towards doing this instead of increasing kinetic energy.
What is breaking attractive forces?
You have two cups of tea. Cup one contains 27mL while cup two contains 28mL. The two cups are at the same temperature, so this cup would have less thermal energy.
What is cup one?
When we place water in the freezer, it loses its heat and becomes ice because of this type of energy transfer.
What is conduction?
This happens to pressure when the volume of a container is increased.
What is decreased?
This graph is what we often use to show the temperature of a substance as it is heated over time.
What is a heating curve?
Convection is caused because adding heat to a substance makes its density do this.
What is decrease?
What is thermal equilibrium?
