The equation for calculating density is this.
What is d = m/v?
Aluminum has a mass of 27 g and a volume of 10 cm3. Calculate the density and include the units. Hint: d = m ÷ v
What is 2.7 g/cm3
One of these objects is the least dense.
What is C?
True or False? A physical change is reversible while a chemical change is not.
What is True?
The state of matter has a definite volume but not a definite shape, particles stay in contact moving.
What is a liquid?
The units for calculating density are this.
What is g/cm3 or g/ml3?
Carbon monoxide gas has a mass of 0.196 g and occupies a volume of 100 mL. Calculate the density and use the correct units. Hint: d = m ÷ v
What is 0.00196 g/mL
A cup of saltwater is heated on a Bunsen burner to evaporate the water, leaving the salt behind. The state change of the water is due to this.
What is thermal energy?
Burning, rusting, changing color, and gas formation are all key indicators of what type of change?
What is a chemical change?
The state of matter with particles that do not stay in contact with one another and move very quickly, shape and volume can change.
What is the a gas?
An object with a higher density than water will do what
What is sink?
A block of aluminum occupies a volume of 15.0 mL and has a mass of 40.5 g. Calculate the density and include the units. Hint: d = m ÷ v
What is 2.70 g/mL
True or False: the boiling and melting points of water will stay the same no matter how much water there is
What is true?
When an ice has thermal energy applied, the state of matter change is an indication of this type of change.
What is physical change?
An example of a liquid changing state into a gas.
evaporation - can vary with answers
The equation to calculate the volume of a regular solid and units
What is L x W x H and cm3
A block of wood is 3 cm on each side and has a mass of 27 g. Calculate the volume and density of the block and include units. Hint: L x W x H to find volume and d = m ÷ v
What is 27 cm3 and 1 g/cm3
True or false: You can add an unlimited amount of a solute to a solvent and it will always dissolve.
What is false?
When a candle is lit, the wick burns, the wax melts, the candle changes shape, and the air around the candle heats up. Which part of this description shows a chemical change?
What is the wick burning?
The state of matter that sound travels the slowest but light travels the fastest.
What is a gas?
The difference between mass and weight
What is gravity
A graduated cylinder has 45 mL of water in it. A rock with a mass of 12 g is placed into the cylinder and the water level went up to 61 mL. Calculate the volume and the density. Hint: measurement after - measurement before to find volume and d = m ÷ v
What is 0.75 g/mL
While oil and water are both liquids, they are different in density because they contain less of these per unit volume.
Baking soda and vinegar are measured and have a total mass of 25 grams. When they are combined, the solution bubbles up and releases a gas. The total mass afterwards is 18 grams. What happened to the other 7 grams?
What is it was released as a gas?
