E2. Exploring and Understanding Concepts
Specific Expectations
Heat in the Environment
E2.1
use particle theory to explain how heat affects the motion of particles in a solid, a liquid, and a gas
E2.2
demonstrate an understanding of various ways in which heat is generated
E2.3
use particle theory to explain the effects of heat on volume in solids, liquids, and gases, including during changes of states of matter
E2.4
explain how heat is transmitted through conduction, and describe natural processes that are affected by conduction
E2.5
explain how heat is transmitted in liquids and gases through convection, and describe natural processes that depend on convection
E2.6
explain how heat is transmitted through radiation, and describe the effects of radiation from the Sun on different kinds of surfaces
E2.7
describe the role of radiation in heating and cooling Earth, and explain how greenhouse gases affect the transmission of radiated heat through the atmosphere
E2.8
identify common sources of greenhouse gases, including sources resulting from human activity, and describe how humans can reduce emissions of these gases
