What does the field of Thermodynamics deal with?
What does the Law of Conservation of Energy states?
The First Law of Thermodynamics states
heat lost by one body is gained by another body
heat lost from one body is not gained by another body.
that both bodies loses heat at the same rate.
heat lost is not equal to heat gain.
Thermal energy is a result of
What is heat?
What is the indirect measurement of an object's thermal energy?
Mass
Volume
Temperature
Density
Hot objects has (a) thermal energy than colder object, which has a (b) thermla energy,
When hot and cold objects are placed in contact, the two objects reach the same (a) , in another word, they both have the same temperature. When hot and cold objects are placed in contact with one another, the (b)
moving particles in the (c) object will begin to bump into the (d) moving particles in
the (e) object making them move faster (and vice versa, the faster particles will then
move more slowly)
What is specific heat?
What is the principle basis for calorimetry?
The creation of energy
The destruction of energy
The transfer of heat
The storage of heat
It takes (a) to raise the temperature of one gram of water by one degree Celsius.
What happens to particles in a hot object compared to a cold object?
They move slower.
They move at the same speed.
They exhibit more rapid motion.
They stop moving.
Heat is measured in units of (a) , and 1 cal = (b) joules/goC. That means it takes 1 calorie or 4.184 joules/goC to raise the termperature of 1 gram of water by (c) degree celsius.
What is the purpose of using the specific heat of water in this experiment?
To measure the density of water
To determine the energy content of charcoal
To calculate the boiling point of water
To find the pH level of water
What happens to the forces that hold atoms together in a fuel during burning?
They become stronger
They are broken and recombine
They remain unchanged
They dissolve in water
In the equation q = mcΔT, what does 'm' stand for?
Mass of the water
Molarity of the solution
Momentum
Magnetic field
In the equation q = mcΔT, what does 'c' represent?
Concentration
Specific heat of the water
Speed of light
Capacitance
What is the role of the calorimeter in this experiment?
To measure light intensity
To transfer heat into the water
To calculate pressure
To determine sound frequency
The initial step in determining the energy content of charcoal in this experiment is (a)
What is the significance of measuring the temperature change in water?
To find the boiling point
To calculate the amount of heat released
To determine the color of water
To measure the volume of water
