Cluster 1 Review

Which tool should be used to measure the amount of heat in a liquid?

• Graduated Cylinder

• Celsius thermometer

• Metric ruler

• Balance scale

Which of the following describes a solid?

• Takes the shape of its container

• Pours easily forming a puddle

• Keeps its shape and size

• Escapes into air from open dish

Students are given a hot plate and a beaker of water and are asked to heat the water and measure its temperature. What other tools and safety equipment do they need for this experiment?

• Spring scale and gloves

• Compass and apron

• Thermometer and goggles

• Hand lens and goggles

Students have a container of water and several objects. The water will help the students observe which of the following properties?

• How quickly the objects heat up

• Whether the objects sink or float

• Whether the objects are made of iron

• The mass of each object

What tool is most useful to determine whether an object is made of iron?

• Magnet

• Microscope

• Thermometer

• Balance

A student took ice cream outside on a summer day. The heat would cause what kind of change?

• A liquid becoming a gas

• A liquid becoming a solid

• A gas becoming a liquid

• A solid becoming a liquid

When an ice cube is placed on the sidewalk on a hot day, what is the series of changes that occur to its physical state?

• Gas-> Solid-> Liquid

• Solid-> Gas-> Liquid

• Solid-> Liquid-> Gas

• Liquid-> Gas-> Solid

Students created a model of the water cycle by heating a beaker of water on a hot plate until it boiled. They carefully held a metal pan of ice cubes where water vapor was rising from the beaker and water drops began to form on the bottom of the metal pan. The water drops formed on the bottom of the pan because –

• the pan was made of metal

• the water vapor cooled

• the ice was a solid

• the hot plate uses electricity

Sometimes a burning candle will have wax dripping down the side. This happens because the heat of the flame –

• turns the wax of the candle to a liquid

• causes water to collect on the candle

• creates tiny air currents around the candle

• uses some of the gases in the air

What causes water to freeze solid when placed in a freezer? The freezer–

• adds heat to the water.

• puts electricity into the water.

• takes heat away from the water.

• does not let light shine on the water.
