Module11
This state of matter has a definite shape and volume.
What is a solid?
Boyle’s Law describes the relationship between pressure and this variable.
What is volume?
A mixture that is evenly mixed throughout is called this.
What is a homogenous mixture?
Energy released into the surroundings is called this type of reaction.
What is exothermic?
This theory says particles must collide in order to react.
What is Collision Theory?
The movement of particles from high concentration to low concentration is called this.
What is diffusion?
Charles’ Law states that volume increases when this increases.
What is temperature?
The amount of solute dissolved in a solution is called this.
What is concentration (or molarity)?
This law states that energy cannot be created or destroyed.
What is the Law of Conservation of Energy?
The minimum energy needed for a reaction to occur is called this.
What is activation energy?
Water sticking to other surfaces is called this.
What is adhesion?
At STP, 1 mole of gas equals this volume.
What is 22.4 liters?
A mixture where substances are visibly different is called this.
What is a heterogeneous mixture?
The amount of heat needed to raise 1 gram of a substance by 1°C is called this.
What is specific heat?
Increasing this usually speeds up reactions because particles move faster.
The strongest intermolecular force among dispersion, dipole-dipole, and hydrogen bonding.
What is hydrogen bonding?
The combined gas law includes pressure, volume, and this variable.
What is temperature?
The ability of a substance to dissolve in another substance is called this.
What is solubility (or soluble)?
A reaction that absorbs energy from its surroundings is called this.
What is endothermic?
A substance that speeds up a reaction without being used up is called this.
What is a catalyst?
The phase change from solid directly to liquid is called this.
What is melting?
In Gay-Lussac’s Law, pressure and temperature are directly related when this is constant.
What is volume?
Molarity is calculated by dividing moles of solute by this.
What is liters of solution?
The energy needed to change a liquid into a gas is called this.
Increasing surface area affects reaction rate by increasing this.
What is the number of collisions between particles?
