Heating up!
Which heats up faster: high or low specific heat?
Low Specific Heat
As volume increases, what will happen to pressure of an ideal gas?
Decreases (Boyles Law)
Exothermic
Gas turning into a Liquid.
Condensation
Gas particles are always in what type of motion?
Random motion
This term defines the amount of heat needed to change the temperature of a certain substance.
Specific Heat
The relationship between temperature and volume is?
Directly Proportional
This type of reaction absorbs heat into the system
Endothermic
Liquid turns into a Solid.
Freezing
Collisions in ideal gases have what types of collisions?
Elastic
Which substance has lower specific heat, Iron or Wood?
Iron
When volume increases, what happens with temperature?
It also increases (Charle's Law)
Endothermic reactions require what?
Energy input
Which reaction is exothermic, freezing or melting?
Freezing
What measurable factor is directly related to kinetic energy?
Temperature
What is the formula for heat energy?
q = mc x ΔT
According the Boyle's Law the volume of a gas will increase and the pressure decreases. What type of relationship is this?
Inversely Proportional
True or false: Exothermic reactions feel cold.
False
Which phase change absorbs energy into the system, boiling or condensation?
Boiling
Describe motion of particles in a solid.
Vibrate in place
If a substance resists temperature change, that means that it has high or low specific heat?
High Specific Heat
What is the formula for an ideal gas?
PV=nRT
Which has more energy in an endothermic reaction: reactants or products?
Products
Reactants → Products + Heat
Which two phase changes release energy into the surroundings?
Melting & Boiling or Freezing & Condesation
Freezing & Condensation
Why do gas particles not lose energy when they collide?
Elastic Collisions
