Answer:
1. SOUND is produced through vibrations.
-TRUE Sound is a type of energy made by vibrations. When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules.
2. Heat flows from an object with LOWER
temperature to an object with HIGHER temperature.
-Heat energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
3. THERMAL energy travels by electromagnetic waves.
-TRUE 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 in the form of visible light. Light is made of waves of different frequencies.
4. Solar panels convert LIGHT energy to electricity.
-TRUE When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
5. VISIBLE LIGHT is the only Em wave seen by naked eye.
-TRUE Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow.
6. When object RELEASES heat, it's energy increase.
-TRUE When the temperature of an object increases, the average kinetic energy of its particles increases. When the average kinetic energy of its particles increases, the object's thermal energy increases.
7. Sound is produced when objects COLLIDE.
-TRUE The fact that sound is a form of energy is most obvious when two objects collide; they lose some of their mechanical energy to sound (in the form of a crash).
8. Matter is made up of molecules that are in RANDOM motion.
-TRUE Mater is like a gas and water are made up of molecules that are moving about constantly and randomly even solid, but solid have more rigid structure than any other matter.
9. HEAT is the energy in transit.
-TRUE Heat may be defined as energy in transit from a high temperature object to a lower temperature object. An object does not possess "heat"; the appropriate term for the microscopic energy in an object is internal energy.
10. Light, heat, and sound energy can be
TRANSFORMED to other forms.
-TRUE Heat, light, and sound are all forms of energy. Heat can be transferred by radiation, conduction and con- vection. Visible light can be produced, reflected, refracted, and separated into light of various colors. Sound is created by vibration and cannot travel through a vacuum.
