Answer:

Evaporation is when water becomes a vapor or a gas. It helps the surface of the Earth from getting too hot and causes the Earths natural greenhouse effect. Hopes this helps! <3

what is the amount of heat energy released when 50.0 grams of water is cooled from 20.0 degrees Celcius to 10.0 degrees celcius
andre [41]

Answer:

The amount of heat released when 50 g of water cooled from 20°C to 10°C will be equal to  - 2093 J.

Explanation:

Given data:

Mass of water = 50 g

Initial temperature= T1 = 20°C

Final temperature= T2 = 10°C

Specific heat of water= c = 4.186 J/g. °C

Amount of heat released = Q= ?

Solution:

Formula:

Q = m. C.  ΔT

ΔT = T2 - T1

ΔT = 10°C - 20°C

ΔT = -10°C

Now we will put the values in formula.

Q = m. C.  ΔT

Q = 50 g .  4.186 J/g. °C . -10°C

Q =  - 2093 J

The amount of heat released when 50 g of water cooled from 20°C to 10°C will be equal to  - 2093 J.

Answer:

Newton's Second Law

Explanation:

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

(I'm going to assume this is an option, but please let me know if it's not!)

Kinetic Energy in Solids, Liquids, and Gases
ELEN [110]

Answer:

The amount of motion of these particles depends on the kinetic energy they possess. Particles with more kinetic energy move faster and farther apart. Particles with less energy move more slowly and stay closer together. The total kinetic energy of all the particles in a sample of matter is called thermal energy. Solids have the lowest kinetic energy as they are tightly packed and vibrate in place. Liquids have comparatively higher kinetic energy so the particles slide past each other. Gases have the most kinetic energy as a result they float around in the air.

Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience inter-molecular forces.
