What happens to the molecules when the liquid changes phase?
Answer:
A phase change is occuring; the liquid water is changing to gaseous water, or steam. On a molecular level, the intermolecular forces between the water molecules are decreasing. The heat is providing enough energy for the water molecules to overcome these attractive forces.

What is the difference between a pure
substance, solution, and mixture?
A pure substance cannot physically be separated, and is made out of one atom (or molecule). Unlike a mixture, however, which are made out of two or more atoms or molecules. A solution in itself is the example of a mixture. (The composition of a pure substance being fixed, and a mixture's being varying depending on which.) And a solution branching off from a mixture into being either homogeneous mixtures or heterogeneous mixtures.

a body of mass 10kg moving with a velocity 4m/s strikes a vertical wall horizontally and returns back with same velocity. find the impulse exerted on the wall if the time of contact is 0.02s
Answer:
1.96Ns
Explanation:
Impulse = Ft = m(v-u)
Impulse = Force * time
Impulse = mgt
Impulse = 10 * 9.8 * 0.02
Impulse = 98*0.02
Impulse = 1.98Ns
Hence the impulse exerted is 1.96Ns

Over many years a limestone surface is exposed to slightly acidic rain. Which result is likely to occur in the limestone
Answer:
calcium carbonate is transformed into calcium sulfate
Explanation:
Limestone stones are formed by calcium carbonate (Ca Co3), when acid rain falls with a little H2SO2, a chemical reaction of the type
Ca Co3 + H2SO4 → CO2 + H2O + CaSo4
Calcium sulfate is much weaker than alatium carbonate, which is why the stone tends to break under its weigh
A cars velocity changes from 0 m/s to 30 m/s in 10 seconds. Calculate acceleration.

About 50 000 years ago, in an area located outside Flagstaff, Arizona, a giant
4.5 x 107-kg meteor fell and struck the earth, leaving a 180-m-deep hole now
known as Barringer crater. If the meteor was traveling at 20 000 m/s upon
impact, with what average force did the meteor hit the earth?
Answer:
F_A =5.625*10^1^6N

Scenario:The owner of Bond's Gym wants your advice. He asks you if you think positive incentives would work better than negative incentives.He is considering these options: - Raising or lowering prices - Applying discounts or fees - Offering exclusive memberships Bond's Gym should use to help solve the problem. If the owner of Bond's Gym raises his prices, the demand for membership will most likely . If the owner of Bond's Gym decides to raise his prices, he could make money per monthly membership.
Answer: Negative Incentives
Decrease
More
Explanation:
Took it on EDG 2021
Price can be defined as the amount of money that must be paid by a buyer (customer) to a seller (producer or owner), so as to acquire goods and services.
This ultimately implies that, it is an amount of money a customer that is buying goods and services are willing to pay to the seller (producer or owner) for the goods and services being offered.
In this scenario, we can deduce the following points:
If the prices of Bond's Gym services are raised, the demand for membership will most likely decrease.If the prices of Bond's Gym services are raised, the owner could make more money per monthly membership.Read more on price here: https://brainly.com/question/11898489

When two things are the same temperature:
А
Heat transfer between the two things stops
B
Their molecules stop moving
They have the same number of molecules
D
Their molecules move at the same average speed
Answer:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.
