100
Energy is doing this when an exothermic reaction is occuring.
What is being released?
100
This is written as c.
What is Specific Heat Capacity?
100
True or False. Heat is a substance.
What is false?
100
This is heat.
WHat is the transfer of energy between to substances?
100
The capacity to do work or produce heat.
What is energy?
200
An ice cube is placed into boiling water. The reaction the ice cube will experience.
What is Endothermic reaction?
200
When ΔT has a negative sign q has this sign.
What is Negative?
200
This happens to a substances temperature when that same substance has an increase of Kinetic Energy.
What is increases?
200
This is written as q in q=mcΔT.
What is energy transfer?
200
The specific heat of water.
What is 4.184 J/g oC?
300
Melting is endothermic or exothermic.
What is Endothermic?
300
You find ΔT by doing this equation.
What is Tf-TI?
300
This happens to the surroundings of an experiment when the system gives off heat.
What is the surroundings gain energy?
300
This is an SI unit for measuring heat.
What is a Joule?
300
The type of reaction showed below.
What is Endothermic?
400
In an exothermic reaction ΔH would be either positive or negative.
What is negative?
400
True or false. When you mix chemicals in a solution just the mass of the water is used.
What is false?
400
What is the temperature of the system doing as a endothermic reaction takes places.
What is increasing?
400
This is the amount of energy required to raise the temperature of 1 gram by 1 Co.
What is specific heat?
400
This is occuring when energy is being taken in by the substance, but the heat is not changing until bonds are entirely broken.
What is the state change from liquid to gas?
500
This is the sign of ΔH when the reaction is favored.
What is negative sign of ΔH?
500
How much thermal energy is required to raise the temperature of 2kg of water by 10 oC?
84,000 J
As the platform being used to create this will not allow me to directly attach the video, you can copy and paste this link to a video of us working out the problem: https://youtu.be/2IQ2pqm1Tx0
500
The state of substances when thermal equilibrium is reached.
What is equal averages kinetic energy?
500
This is change is system enthalpy.
What is ΔH?
500
The heat required to raise the temperature of 1 gram of water by 1 °C.
What is a Calorie?
