The statement that describes the energy changes associated with evaporation and boiling is that atoms gain energy during evaporation and boiling.

<h3>What is evaporation?</h3>

Evaporation is defined as process by which a solution changes from its liquid state to gaseous state.

Boiling is defined as the heating of water to a point that the vapor pressure is equal to the pressure of the gas above it.

In both phase transition stages, the molecules gain enough energy to change its state to another state.

Choose two features of the sun and describe them.
Fofino [41]
Okay, I am going to use solar prominence and solar flares.

So, Solar Prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominence are anchored to the Sun's surface in the photo-sphere, and extend outwards into the Sun's corona.

A solar flare is a sudden flash of brightness observed near the Sun's surface. It involves a very broad spectrum of emissions, requiring an energy release of up to 6 × 10²⁵ joules of energy (roughly the equivalent of 160,000,000,000 megatons of TNT, over 25,000 times more energy than released from the impact of Comet Shoemaker–Levy 9 with Jupiter).

Laura sees a horse pulling a buggy. She wonders how it can accelerate if the action of the horse pulling the cart would cause an
cricket20 [7]

Answer:

The net forces exerted on the horse and cart are not the same, so they are not balanced forces.

Explanation:

Using newton laws,

ΣF = ma

The two forces acting on the body is the forward force by the horse and the frictional force opposing the forward force

F-Fr= ma

Therefore,

F=ma+Fr

So the forward (by horse) is more than the opposite reaction (by cart).

The only time the forward force and the opposite reaction are the same is when a=0, I.e, the body is not moving at all or the body is moving at constant velocity.

in the 2008 olympics,Jamaican sprinter Usain Bolt shocked the world as he ran the 100 meter dash in 9.69 seconds. Determine Usai
Nat2105 [25]

His average speed is 10.3 m/s

Explanation:

In this problem, Bolt is moving by uniform motion (=constant velocity and constant speed), so its average speed is given by

speed = \frac{d}{t}

where

d is the distance covered

t is the time taken

In this race, Bolt has covered a distance of

d = 100 m

In a time of

t = 9.69 s

Therefore, his average speed is

speed = \frac{100}{9.69}=10.3 m/s
