Heat is always transferred from __________ to __________ environments.
dense, empty |
|
empty, dense |
|
warmer, cooler |
|
cooler, warmer |
Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.
Materials like metals that transfer heat efficiently are called:
insulators |
|
reflectors |
|
conductors |
|
refractors |
