Which statement about a closed system is correct?
Destroys energy through heat
Exchanges energy with surroundings
Transfers energy only within itself
Creates new energy internally
Law of Conservation of Energy states:
Energy is not created or destroyed
Energy can vanish in open systems
Heat always flows to warmer objects
Mass converts into speed directly
A thermal insulator is a substance that:
Does not conduct heat well
Conducts electricity quickly
Converts light to heat efficiently
Stores kinetic energy strongly
Mass is measured in:
Meters per second
Newtons per meter
Joules or calories
Grams or kilograms
Joules (J) are the unit of:
Temperature
Mass
Energy
Speed
Speed is calculated by:
Multiplying mass by gravity
Adding height to weight
Dividing distance by time
Dividing energy by area
Which formula represents mechanical energy?
ME = PE + KE
ME = m × v
ME = m × g × h
ME = KE − PE
Weight relates to mass and gravity as:
Weight = mass × gravity
Weight = mass ÷ height
Weight = gravity ÷ mass
Weight = mass + gravity
Particles in matter always have kinetic energy because:
They are massless in space
They are electrically neutral
They absorb infrared light
They are always moving
Which statement(s) are true for thermal energy?
Same as temperature measure
Is total kinetic energy of particles
Equals average particle speed
Depends on how much substance
