Temp
The scale of temperature used by the vast majority of the world and the scientific community
What is Celsius?
What is the transfer of heat through contact (atoms colliding against one another)
The definitions of system and surroundings
What is the object of our focus and everything else around that object
The melting and boiling points of water, in degrees Celsius.
What is 0 and 100 degrees
Each of the variables in the formula represents
q=mcDeltaT
What is q= heat, m = mass, c = specific heat capacity, delta T = change in temperature
Delta T = final - initial temperature
The flow of heat follows this path
What is from a hot object to a cold object
The phase(s) of matter which conduction is the WORST for
What is gases and liquids
The difference between an exothermic and an endothermic reaction
What is: exothermic reactions has energy move from the system to the surroundings. Endothermic reactions has energy move from the surroundings to the system.
The temperature of a boiling pool of water
What is 100 degrees Celsius
The units for each of the variables in the formula
q=mcDeltaT
What is q= Joules (J), m= grams (g), c = J/ g *° C, delta T = °C
The chemical definition of temperature
What is the energy associated with the movement of atoms.
The definition of radiation heat
What is heat through electromagnetic waves such as microwaves or infrared radiation
The definition of heat capacity
What is how much energy is required to raise the temperature of something
The reason the temperature does not change during a phase change
What is the energy goes to breaking bonds instead of raising temperature
The difference between energy being absorbed and released in a reaction
What is energy absorbed is an endothermic reaction, energy released is an exothermic reaction
The chemical definition of heat
What is the transfer of thermal energy from one object to another
The definition of convection
A cycle of heating where a liquid/gas warms up, rises, pushes down cold liquid/gas. This gets heated until the entire liquid/gas is heated/cooled
The difference between heat capacity and specific heat (capacity)
The parentheses are there because sometimes I use specific heat instead of specific heat capacity although they mean the same thing.
What is specific heat capacity is how much energy is required to raise the temperature of 1g of something 1 degree celsius. It is more specific because it compares mass and leads to better comparisons.
The heat of fusion's definition.
Melting is a (endo/exo)thermic reaction
2 parter
The amount of energy required to melt an object. This energy is absorbed so endothermic.
The sign (positive or negative) of endothermic and exothermic reactions
What is exothermic reactions have a - heat (q=negative number)
Endothermic reactions have a + heat (q=positive number).
The definition of Thermal equilibrium. Give an example
What is over time two objects will become the same temperature
Example: water in fridge will become cold
What is hot air is less dense than cold air because more temperature means more movement, more movement means atoms are spread out more. Less dense liquids/gases rise to the top over more dense objects
The estimated temperature if you mixed 10g of 10 degree water and 50g of 50 degree water.
What is approximately 40 degrees
The formula for calculating how much energy is released to freeze a liquid, given a mass.
Heat of solidification x mass = energy released
Assuming no energy is lost to the surroundings, the mathematical relationship between the energy lost by a warmer object and the energy gained by the colder object in heat transfer.
Hint: We used this in our lab calcualtions
What is q cold = -q warm (they are equal in magnitude, opposite in sign)
