Transfer mechanism of heat through electromagnetic waves, such as the heat we feel from the sun or a fire. In this process, heat energy is emitted from a hotter object in the form of electromagnetic waves and is absorbed by cooler objects. Does not require a medium to transfer heat and can occur through a vacuum.

Physical quantity that expresses the hotness or coldness of an object or a system. It is a measure of the average kinetic energy of the particles that make up the object or system.

Is defined as the force exerted by the molecules of a matter on the walls of the container in which it is contained. It is proportional to the average kinetic energy of the molecules and their number density.

Is defined as the total space occupied by the total amount of molecules. Is a measure of the physical size of the container in which the matter is contained.

Scale of temperature that was originally defined by setting 0 (zero) as the temperature at which water freezes and 100 as the temperature at which water boils at sea level atmospheric pressure.

On this scale, a scientist used a mixture of ice, water, and ammonium chloride to define his zero value, then assigned a temperature of 96 to the human body temperature, which he measured using a thermometer placed under his arm.

Defined his temperature scale (SI unit of temperature) based on the concept of thermodynamic temperature. He used the idea of an "absolute zero" temperature, which is the temperature at which all molecular motion stops.

Is the tendency of materials to change in volume, length, or shape in response to a change in temperature. When materials are heated, their particles begin to move more quickly and occupy a larger space, leading to an increase in volume or length.

Is defined as the transfer of energy from a hotter object to a colder object, resulting in a temperature change.

It refers to the amount of heat energy required to change the state of a substance without changing its temperature. During a phase change, the energy added or removed from the substance goes towards breaking or forming intermolecular bonds between the molecules rather than increasing or decreasing the kinetic energy of the substance.

Transfer mechanism of heat between objects in direct contact, such as a metal spoon placed in a hot cup of coffee. In this process, heat is transferred from the hotter object to the cooler one by the transfer of kinetic energy between the molecules of the objects.

Transfer mechanism of heat through the motion of fluids, such as air or water. When a fluid is heated, its density decreases and it rises, while cooler, denser fluid sinks. This creates a “circular” motion which transfers heat from one location to another.

Transfer mechanism of heat through electromagnetic waves, such as the heat we feel from the sun or a fire. In this process, heat energy is emitted from a hotter object in the form of electromagnetic waves and is absorbed by cooler objects. Does not require a medium to transfer heat and can occur through a vacuum.

This law of thermodynamics states that if two objects are in thermal equilibrium with a third object, then they are in thermal equilibrium with each other. This means that if you touch two objects and they feel the same temperature, and each of these objects is also in thermal equilibrium with a third object, then all three objects are at the same temperature.

This law of thermodynamics states that energy cannot be created or destroyed, only transferred, or transformed. This means that the total amount of energy in a system remains constant, even if the energy is transferred from one object to another or transformed into a different form of energy.

This law of thermodynamics states that in any energy transfer or transformation, the total entropy of a closed system always increases over time. This means that energy tends to spread out and become more disordered over time, and that it is impossible to convert all heat energy into work without some of it being lost as waste heat.

Which is an example of decreasing entropy in a closed system?

How much energy is required to convert 3 kg of water at 20°C to steam at 100°C? (The specific heat of water is 4.184 J/g°C and the latent heat of vaporization is 2257 J/g)

This is what happens to an object when the gravitational force is stronger than the buoyant force.

"The ability of a a fluid (liquid or gas) to exert an upward force on the object immersed in it" is the BEST definition for which of the following terms:

"The buoyant force on an object is equal to the weight of the fluid displaced by the object" is the basis for which of the following principles:

In order to make a cup of milk coffee at 78°C, 200 g of coffee is mixed up with 40 g of milk. If the original temperature of the coffee is 80°C, find the original temperature of the milk. Assume that there is no heat lost to the surroundings. Given that the specific heat capacity of coffee and milk are 4000 J kg^-1 °C^-1 and 3900 J kg^-1 °C^-1 respectively.

Mix 700 g of water at 100°C with 500 g of water at 30°C. Find the final temperature of the water.

【specific heat capacity of water = 4200 J/kg°C】
