How many significant figures are in 0.0089?

Two Significant Figures

100

Made of one type of atom.

What is an en element?

100
Opposite of evaporation.
What is condensation?
100

Where do we find the specific heat of water?

Table B

100

What is happening to the motion of the particles as we go from solid to liquid to gas?

Motion increasing/ particles moving faster

200

How many significant figures are in 0.007300?

Four Significant Figures

200

Two or elements chemically combined.

What is a compound?

200
Another word for melting.

What is fusion?

200

What substance in Table H has the highest intermolecular force?

Ethanoic Acid

200

What is happening to the spacing of the particles as we go from gas to liquid to solid?

Spacing decreasing/particles coming together.
300

How many significant figures are there in 107, 851,000?

Six significant figures

300

What are the hints for a chemical change?

Hint: Burning or "reacts" with

300

Process of solid straight to a gas.

What is sublimation?

300

What is the normal boiling point of ethanol?

79C

300

What is happening to the KE and PE during a phase such as a solid? (Think line going up or going down in a heating and cooling curve respectively.)

Heating Curve - KE increasing/PE constant

Cooling Curve - KE decreasing/PE constant

400

How do we find the volume of a regularly shaped object?

V= l x w x h

400

Process used to separate mixtures by difference in boiling points.

What is distillation?

400

Drawing for solid, liquid, gas.

Drawing

400
What is the measurement of the average Kinetic Energy?
Temperature
400

What is happening to the KE and PE during a phase change such as evaporation? (Think line is straight in a heating /cooling curve.)

Heating Curve: KE constant / PE increasing

Cooling Curve: KE constant / PE decreasing

500

How do we find the volume of an irregular object (like a rock)?

Water displacement method

500

Draw a mixture of compounds.

Drawing

500

What is happening to the heat as we go from a gas to a liquid to a solid?

It is being released - exothermic reaction.

500

How do I determine which heat equation to use when solving a heat problem?

Must determine whether temperature is changing or constant. If constant then what phase change is the substance undergoing.

500

How do we determine whether is a higher Heat of fusion or Heat of vaporization?

It is based on what takes longer - does it take longer to melt or evaporate. (Doesn't have anything to do with the temperature.)
