Which of the following is an example of what happens when water freezes? A. Ice formed floats B. Ice formed sinks C. Ice does not form
What is a cloud of gas and dust in space, often where stars are born? square
What receives radio waves from space objects such as quasars? GPS equipment Landsat satellites VI BI equipment navigation satellites
Which term is described when measuring the number of liters of gas trapped in a bottle? pressure mass volume horespower
The Sun fuses: helium into hydrogen hydrogen and methane hydrogen into oxygen helium and oxygen
Water has the property of having a high specific heat. Which of the choices represents this property? Water in lakes and streams flows to the oceans faster causing more erosion. All marine animals can live at any ocean depth because the water is the same temperature. Pond water cools down quickly at night causing animals to come out of hiding. Pond water temperatures change little from day to night so pond organisms aren't exposed to extreme temperatures differences.

Which word or phrase best describes entropy? disorder order kinetic energy force
What are most semiconductors made from? aluminum copper iron silicon
At which temperature does all molecular motion stop? OR $0^{\circ }C$ OK $0^{\circ }F$
Which statement about the volume and pressure of a gas is the most accurate? Volume of a gas is directly proportional to pressure of that gas in any container. Volume of a gas is inversely proportional to pressure of that gas in any container. Volume of a gas is always greater than pressure of that gas in any container. Volume of a gas is equal to pressure of that gas in any container.
