Answer:
They gain kinetic energy
Explanation:
When the temperature of the particles in a substance rise, its internal energy increases. This internal energy is thus translated to kinetic energy of the particles in the substance. If the substance is a solid, as the kinetic energy increases, the vibrations of the particles of the substance increases causing it to undergo a change of state to liquid when the temperature reaches its melting point.
This change of state also occurs from the liquid state to the gaseous state as the internal energy of the substance, and thus the kinetic energy of the particles increase when the temperature reaches the substance's boiling point.
<u>So, as the temperature of a substance rises, the particles of the substance gain kinetic energy.</u>
Answer:
it shows that co2 is absorbed by the atmosphere.
when the animals respire they produce co2 which is release in atmosphere and in presence of sunlight and chlorophyll the plants manufacturs the food and releases the oxygen in the atmosphere .

Initial velocity(u) = 11.2 m/s.
Final velocity(v) = ?
acceleration(a) = 10.2 m/s²
Using kinematic equation v = u + at
v = 11.2 + 10 x 8 = 11.2 + 80 = 91.2 m/s.
Therefore final velocity is 91.2 m/s.
The oxygen attracts the shared electrons more strongly than the hydrogen atoms do.
The mutual forces of gravity between the Earth and an object on or near
its surface are (<em>mass of the object</em>) x (<em>acceleration of gravity on Earth</em>).
These two forces are equal, and we call their strength the "weight" of
the object. It's the number shown on the scale as long as nobody has
their thumb on the scale. In this problem, the force is 45N . (That's
about 10.12 pounds.)
The acceleration of gravity on Earth is about 9.8 meters per second² .
So 45N = (mass in kilograms) x (9.8 meters per second²)
Divide each side by 9.8 : Mass = 45/9.8 = <u>4.59 kilograms</u> (rounded)
