Delimiter between question and answer:

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.

How are deposition and sublimation similar?
They both involve skipping a step when changing states of matter.
What is a word that means changing from a liquid to a gas?
boiling/evaporating/vaporizing
What is a word that means changing from a solid to a liquid?
melting
True or False? Heating or cooling will cause the volume of a substance to change.
True
True or False? Heating or cooling will cause the mass of a substance to change.
False
How is ice an exception to the thermal contraction/expansion rule?
When water freezes to ice the volume increases rather than decreases.
What happens to most substances when they get colder?
They contract/particles vibrate more slowly/eventually freeze.
How have engineers avoided issues to bridges caused by thermal expansion and contraction?
expansion joints
Thermal expansion and contraction can strain bridges. Explain what is actually causing the bridge to weaken or break?
The bridge changing length straining the structural components.
What causes thermal expansion?
adding heat/energy/increase in temperature/particles vibrating more rapidly
What will most solids do when they are heated?
melt/expand
True or False? Water changes to ice at 32 degrees Celsius.
false - it's 32 degrees Fahrenheit
Why is frost an example of deposition?
Because water vapor changes directly to a solid skipping the liquid state.
Why is dry ice an example of sublimation?
Because it changes from solid to a gas skipping the liquid state.
How is sublimation different from vaporization?
Sub. - solid to gas Vap. - liquid to a gas
Why do different kinds of matter change states at different temperatures and at different rates?
Each change depends on the particles and the forces.
What causes the water vapor to condense on the outside of a lemonade pitcher on a hot day?
The coolness of the pitcher removes the energy from the water vapor causing it to change to water droplets.
What happens to a gas when energy is removed from a gas?
It turns to a liquid/condenses.
How are boiling and evaporation different?
Boiling is rapid while evaporation is slow/gradual.
How are boiling and evaporation the same?
They both change a liquid to a gas.
What happens to a substance’s particles when energy is added?
They speed up.
How do you change a liquid to a solid?
Remove energy.
When will a solid change to a liquid?
When enough energy (heat) is added.
What's wrong? Matter is often conserved in a physical change?
Often should read always.
Fill in the Blank: A change of state is a _____________ change.
physical
