What temperature does water freeze at in celsius?

What is 0* C

100

The measure of average kinetic energy of matter is?

What is temperature

100

What is the tool used to measure weight? What is the unit?

What is a scale or spring scale? It is measured in Newtons

100

What is the formula for density?

Density = mass/volume

100

0.0987 hm = __ cm

987 cm

200

In theory, what is the lowest possible temperature that scientists believe is possible?

What is 0 Kelvin

200
Earth's gravitational attraction acting on the mass of an object is known as...

What is gravity

200

What tool is used to measure mass? What is the unit for mass?

A triple beam balance. It is measured in grams or kilograms.

200

What are the units for density?

g/cm ^3 or g/mL

200

90.78 cg = __ g

0.9078 g

300

What is the boiling point of water in fahrenheit?

212 degrees F

300

What is heat? How is it transferred?

Heat is thermal energy that is transferred from matter at a higher temperature to matter that is at a lower temperature

300

What is the first thing you do before you use a balance?

Make sure all of the riders are at 0 and it is level.

300

If the mass of an object is 45 g and the volume is 5 cm^3, what is the density?

9 g/cm^3

300

98.099 kL = __ cL

9,809,900 cL

400

What is temperature?

The measure of the average kinetic energy of a material

400

What is absolute zero?

The temperature at which no more energy can be removed from matter

400
You have 2 objects that are the same size- Object A has a mass of 1487 g and Object B has a mass of 878 g. Which object do you think has the greater density and why?

Most likely object A because it has more mass, but it depends on the volume.

400

Will an object with a density of 9g/cm^3 sink or float in a liquid with a density of 10 g/mL? What about in water?

It will float because it is less dense than the liquid. However, it will sink in water because it is more dense than 1 g/mL

400

0.65 dag = __ hg

0.065 hg

500

What temperature does water freeze at in Fahrenheit? 

32 degrees

500

The temperature scale in which the interval between the freezing point of water is divided into 180 equal parts is called the

Fahrenheit scale

500

What is the difference between weight and mass?

Mass is the amount of matter in an objec and it never changes. Weight depends on the pull of gravity on an object and therefore can change.

500

What is the mass of an object with a density of 10g/cm^3 and a volume of 4 cm^3?

The mass is 40 g.

500

87.9890 mg = __ dag

0.00879890 dag
