Temperature and Heat Quiz
Terms in this set (47)
caused by internal motion of atoms/particles
the measure of the average of the kinetic energy of particles
3 ways to measure temperature
Fahrenheit, Celsius and Kelvin
Kelvin- Absolute zero
lowest theoretical possible temperature
f= (1.8xC) +32
C= (F-32) / 1.8
if objects are heated they expand
the amount of heat energy need to raise the temperature of 1g of that substance 1 Celsius
Heat energy unit
the amount of heat energy needed to raise the temperature of 1 gram of water 1 celsius
Highest specific heat
heat gain or loss
mass x triangle t x specific heat
measure specific heat
Particles that make up matter are in constant motion
the faster particles move the less kinetic energy they have
temperature is the measure of the average kinetic energy of the particles in an object
when temperature increase, the average kinetic energy of the particles decrease
the thermal energy of an object is the total energy of the articles in a material
a thermometer is used to measure the specific heat of a material
thermal energy flows from a higher temperature to a lower temperature
heat is measured in newtons
the same amount of different materials need the same amount of heat to have the same change in temperature
the amount of energy it takes to raise the temperature of 1 g of a material 1 Kelvin is the specific heat of the material
water has a relatively low specific heat
materials with a high specific heat can absorb a lot of energy and show little change in temperature
In this equation, what does q represent?
heat gain or loss
what does m represent?
what does Tf represent?
what does Ti represent?
What does c represent?
molecules of a substance are in motion (blank)
all of the time
temperature is relative to the (blank)
on the (blank) temperature scale, freezing is 0 (blank)
on the (blank) temperature scale, water boils at 212 (blank)
one liter of water at 50 Celsius has (blank) kinetic energy as 2 liters of water at 50 Celsius
thermal energy is a measure of the (blank) energy of a substance
potential and kinetic
100 ml of water at 20 Celsius has (blank) thermal energy than 500 ml of water at 20 Celsius
The temperature of a warm spring day might be 75 Fahrenheit. What is that in Celsius and in Kelvin?
In Celsius the temperature would be 24 Celsius and in Kelvin it would be 297 Kelvin
