Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What is the equation for pressure?
pressure = force/ area
A person at a fancy dress party is wearing a trainer on one foot and a shoe with a stiletto heel on the other! Which exerts the most pressure on the ground?
high heel
What would happen to the gas pressure in a container if the temperature increased?
the pressure would increase
Explain why water is a liquid at room temperature (refer to its melting and boiling point)
Water has a melting point of 0°C, and a boiling point of 100°C. Room temp is ~22°C, by which time water has passed its melting point but has reached boiling
Describe how temperature can affect the rate of diffusion.
As temperature increases, the kinetic energy of the particles increases. This causes them to move around more quickly and diffuse from one place to another.
What is meant by ‘conservation of mass’?
In a chemical reaction, the overall mass of the reactants is always equal to the overall mass of the products.
Describe how gas pressure is caused in a sealed container.
The particles move about at all different speeds and in different directions; they will frequently collide with the walls of their container and exert pressure
Identify 2 properties of a gas and provide reasons for these properties.
Can be compressed, can flow, take the shape of their container, low density
Identify 2 properties of a liquid and provide reasons for these properties.
Cannot be compressed, can flow, change shape to fit their container
Identify 2 properties of a solid and provide reasons for these properties
Cannot be compressed, High density, Fixed shape
Define diffusion.
The movement of particles from an area of higher concentration to an area of lower concentration, down a concentration gradient
Name the four changes of state
Changes of state are melting, boiling, condensing, freezing
Identify the 3 states of matter
solid, liquid, gas
