Calorimetry
This is the definition of calorimetry.
What is the process of measuring the amount of energy released or absorbed by a substance?
This is how many significant figures in 0.006 g.
What is 1?
This is the definition of heat.
What is the amount of thermal energy transferred?
This is the base unit for measuring a gas' volume.
What is a liter ( L ) ?
These are the four quantities for describing a gas.
What is pressure, volume, temperature, and number of particles (moles)?
These are the units specific heat is measured in.
What is J/(g*°C ) or J/(g*°K) ?
This is the number 2,876,030,000 converted to scientific notation.
What is 2.87603 x 109 ?
This is specific heat capacity.
What is the amount of energy it takes to increase one gram of a substance by one degree?
This is an imaginary gas that conforms perfectly to all the assumptions of the kinetic molecular theory.
What is an ideal gas?
This is the relationship between pressure and volume.
What is an inverse relationship?
A block of hot metal is dropped into water at 25.0 degrees Celsius. Over the next minute, a student makes these observations of the water's temperature:
25.0
27.8
29.3
29.5
29.4
28.6
This is the temperature the metal and water reached thermal equilibrium, based on the data.
What is 29.5 degrees?
This is 190 x 190. .
What is 36,000 ?
This is the process that is happening when the potential energy of particles changes but kinetic energy remains constant.
What is a phase change?
This is the symbol of the ideal gas constant.
What is " R " ?
This is the change in pressure when a gas is held at constant temperature, but its volume increases.
What is decreases?
This is the heat when 30.0g of dry ice is cooled from -78.5 degrees Celsius to -125.0 degrees Celsius (the specific heat of dry ice is 0.815 J/(g*C).
What is -1,140 J ?
This is 5,899.9 + 10.58.
What is 5,910.5 ?
This is the measurement of the force of collisions particles of a gas have with the walls of their container over an area.
What is the definition of pressure for a gas?
These are the conditions on a phase chart where a real gas acts the most like an ideal one.
What is high temperature and low pressure?
This is the issue with the following student's work:
P1 / T1 = P2 / T2
1 atm / 30 C = x / 90 C
Multiply both sides by 90 C .
3 atm = x
What is the student has to use Kelvin?
A 150. g block of copper is heated to 95.0°C and then placed into 220 g of water at 25.0°C. The water and copper reach thermal equilibrium at 30.0°C. Assuming no heat is lost to the surroundings, this is the specific heat capacity of copper.
What is 0.47 J/(g*C) ?
This is 9.811x103 x 1.7x104 .
What is 1.7x108 ?
This is the quantity of how much energy it takes a sample to undergo the phase change from solid to liquid.
What is heat of fusion?
These are three of the four conditions of the Kinetic Molecular Theory.
What are:
- particles in constant, random, straight movement
- collisions are fully elastic
-there are no attractions between particles or their container
- the volume of the particles is negligible
?
This is the factor the volume of a gas would increase by if you multiplied its temperature by 4 and its pressure by 2 (use the combined gas law!).
What is a factor of 2?
