VII PHYSICS-WHO AM I?

I am a force that resists the motion of objects sliding or rolling over a surface. I can make it harder to move things. What am I?

I am the change of state from a liquid to a gas. I occur when the temperature of a liquid is raised. What am I?

I am the smallest particle of an element that retains the chemical properties of that element.

I am a form of energy that travels in waves. I am invisible, but I can be felt as heat. I also cause sunburn. What am I?

I am a device used to measure temperature. I usually have a scale that shows how hot or cold something is. What am I?

I am the measure of the amount of matter in an object. I am often confused with weight, but I do not change with location. What am I?

I am the change of state from a solid to a liquid. You can see me when ice melts into water. What am I?

I am the ability to do work. I can be stored in different forms, like chemical energy or kinetic energy. What am I?

I am a simple machine with a flat surface that is slanted. I help lift heavy objects with less force. What am I?

I am a type of simple machine, and I consist of a rigid bar that rotates around a fixed point called a fulcrum.

I am a simple machine that makes lifting heavy objects easier. I am made up of a rope and a wheel. What am I?

I am the amount of space an object takes up. I can be measured in liters or cubic meters. What am I?

I am a property of materials that determines how much heat can pass through them. I help keep your house warm or cool. What am I?

I am the change of state from a gas to a liquid. I can be seen when water vapor condenses on a cold surface. What am I?

I am the force that pulls objects towards the Earth. I can make things fall to the ground. What am I?

I am a type of energy that is stored in an object due to its position. I can be seen when you stretch a rubber band or lift an object. What am I?

I am the element that makes up 78% of the Earth’s atmosphere and is essential for protein and DNA synthesis.

I am a type of energy that causes a change in position or motion. I can be stored in moving objects. What am I?
