(a)
Conduction is heat being transferred when 2 objects are directly touching.
(b)
Convection is when hot air rises and cold air sinks.
(c)
Radiation is heat transfer without a medium.
Did you know that hot flows towards cold because in conduction heat always flows towards cold.
According to convection hot air flows upwards and cold air flows downwards.
(b)
The Three units used to measure temperature are celsius, fahrenheit and kelvin.
Did you know?
Did you know that when you heat water in a pot the molecules start to heat up they start to vibrate very quickly, and that creates heat, and then the burner creates heat and through conduction the the pot starts to warm up. Next the molecules in the pot start to vibrate. Then the water in the pot also starts to warm up, the water starts heating all the water using a process called convection. Finaly the molecules flow in circles, hot air rise and cold air sinks.
(b)
It is a common misconception that you can touch heat however you can’t. You can touch an object that is hot but you cannot touch heat.
(c)
Radiant energy moves without a medium.
(a)
It creates heat on the earth, and sustains plant life on earth.
(a)
We use radiation to create solar energy.
Fun Fact!
Water boils because of the molecules moving so quickly in the water. The Warmer an object is the faster the molecules moves.
(a)
The definition of temperature is that it depends on the average kinetic energy of the atoms and molecules in a substance. Temperature measures the heat of an object.
(c)
Convection happens because when you are holding the ice your hand is warmer and it transfers heat to the ice.
(b)
4.27 tons of mass are converted to energy each second.
(c)
It creates heat on the earth, and sustains plant life on earth.
(d)
You could see geothermal energy in the earth’s plate tectonics.
Thermal Equilibrium is when 2 objects with different temperatures become the same temperature over time.
