What is heat?

Liza holds sorbetes colder than her hand. Which direction does the net energy transfer take?

Which SI unit measures energy transferred between objects at different temperatures?

What does temperature indicate about a substance's particles?

What is the SI base unit for temperature?

Read the thermometer. What temperature does it show?

A room-temperature spoon is placed in hotter water. What happens to the spoon before both reach the same temperature?

Two objects in contact reach the same temperature. What happens to the net energy transfer between them?

Which pair consists only of good thermal conductors?

Which pair consists only of common thermal insulators?

Which property helps a cooking pot distribute energy quickly through its material?

A metal spoon and a wooden spoon have been in the same room overnight. Why can the metal feel colder?

Maya compares how quickly energy travels through rods made of different materials. Which procedure makes the comparison fair?

Why are many cooking-pot handles covered with wood or plastic?

How does wall insulation usually affect electricity use in an air-conditioned home during hot weather?

The handle of a metal spoon becomes warmer while its other end rests in hot soup. Which method carries energy along the spoon?

Water heated at the bottom of a pot rises while cooler water moves downward. What process carries energy through this circulation?

Which method brings energy from the Sun to Earth across space?

What does thermal radiation require to travel?

During conduction along a solid glass rod, how do its atoms transfer energy?

Why does warmed air often rise through surrounding cooler air?

Two connected jars contain 50 °C water above 20 °C water. Why is this arrangement less likely to produce strong natural circulation?

Paper clips are attached with equal small blobs of wax along a metal spoon. One end is heated. Which clip should fall first?

Which tool should Maya use to compare how hot two samples are instead of relying on touch?

Which surface is generally the best absorber and emitter of thermal radiation?

A shiny foil sheet faces a hot surface across an air gap. How can it reduce energy reaching the material behind it?

Why does a narrow sealed air gap between window panes help reduce energy transfer?

Warm outdoor air enters an air-conditioned classroom through an open door. How does this affect the energy needed to maintain the indoor temperature?

Which description defines a geological fault?

Which stored energy is released to produce seismic waves when stressed rocks suddenly slip along a fault?

Use the arrows and displaced layers in the model. Which type of fault is shown?

Which stress usually produces the movement shown in this model?

In this side view, the dot means movement toward you and the cross means movement away. Which fault type does the model show?

What is the specific name for the shallow-angle fault shown by this model?

What do geologists call the rock block above an inclined plane along which slipping occurs?

Geologists find evidence that a fault moved 2,000 years ago. Under PHIVOLCS classification, how should it be categorized?

Which earthquake-and-volcano belt follows the ocean rim shown on this map?

Why does the Philippines experience frequent tectonic earthquakes?

Which type describes the major movement along the Philippine Fault Zone?

A PHIVOLCS map shows an active fault crossing a proposed house site. Which earthquake hazard is most directly associated with building across that fault?
