Is a solid changing from a liquid to a gas a physical or chemical change?
The change of a liquid to a gas is a physical change because its chemical properties do not change. Molecules of the liquid are just moving farther apart, therefore turning into a gaseous state.
What does Gravity have to do with hot air rising?
The density of air changes with change of temperature, therefore changing it's mass. In other words, the molecules that make up the composition of air move farther apart with a rise in temp and, of course, just the opposite with a decrease in temp. Since temperature changes the mass of air, gravitational pull from the earth will change proportionately.
Write the kind of change against the following 1. tearing of paper 2.rottening of eggs 3.Melting of wax 4.Burning of wax candle 5.Rusting of iron 6.curdling of milk 7.Growth in a child?
1. This is ambiguous it could be said to be a chemical change because the intermolecular forces between strands of cellulose are broken. however simplistically it might be said to be merely physical. 2. Chemical change. 3. Physical change specifically a change in state of matter. 4. Chemical change. This is a combustion reaction. 5. Chemical change. Iron (Fe) reacts with oxygen (O) 6. Chemical change. This is a modification of the proteins in the milk usually by the enzyme trypsin. 7. again a bit ambiguous As humans are made up of chemicals and nutrients need to be digested and deposited for growth it is justifiable chemical however simplistically it is physical.
Where are the load effort and fulcrum located on a second class lever?
No, the function of the fulcrum remains the same The only change would be the ratio of force to load The closer the fulcrum is the the load, the less force required to lift it The farther away the fulcrum is from the load, the more force required to lift it
What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
An area of wave washed sediment along a coast is?
A beach is an area of wave-washed sediment along a coast. It typically consists of sand or pebbles that have been deposited by the action of waves and currents. Beaches are dynamic environments that can change in response to storms, tides, and other factors.
