Which Is The Best Example Of The Law Of Conservation Of Energy? What is the best example of the law of conservation of energy? If a pendulum is one meter off the ground at one end of its swing, it can never be more than one meter (The law of conservation of energy states that
Why Does Current Produce Heat? In metal conductors, electrical current flows due to the exchange of electrons between atoms. As electrons move through a metal conductor, some collide with atoms, other electrons or impurities. These collisions cause resistance and generate heat. Why heat is produced by electric current? When an electric current is passed through
Which Of The Following Has Low Specific Heat? Specific heat is how much heat energy is needed raise the temperature of a substance. Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats.
Which Of The Following Is An Example Of Chemical Energy? Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car’s engine.
Which Of The Following Is An Example Of Radiant Energy? Some examples of radiant energy include: The heat emitted from a campfire. Emission of heat from a hot sidewalk. X-rays give off radiant energy. What are examples of radiant energy? Examples of radiant energy include the warmth that radiates from a hot stove and the
Which One Is Greater CP Or CV? The heat capacity at constant pressure CP is greater than the heat capacity at constant volume CV , because when heat is added at constant pressure, the substance expands and work. Is Cv less than CP? Because work is done to the contracting water, less heat is required
Which Two Factors Affect The Amount Of Energy An Appliance Transfers? The thermal energy of an object depends on its temperature and mass. The higher the temperature of a substance, the more thermal energy it has. For the same temperature, a substance with a higher mass will also have more thermal energy. Which 2 factors
When Light From The Sun Warms The Ground The Transfer Of Heat Energy Is Called? Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Which energy transfer warms Earth from the Sun? The Sun’s energy reaches Earth
What Is Heat Capacity Of Calorimeter? The heat capacity of the calorimeter is the quantity of heat absorbed by the calorimeter for each 1°C rise in temperature. The heat capacity of the calorimeter must be determined experimentally. The easiest process is to study the mixing of warm and cold water. What is the heat capacity
Which One Is Not A Similarity Between Heat And Work? Both are energy interactions. Both are transient phenomena. Both are boundary phenomena. Both represent energy crossing the boundary of the system. They are not the property of the system. Both are path functions. What is different between heat and work? Work (W) Heat (Q) Requires
