Answer:
As the temperature rises the solubility of all gases in water also will decrease.
Explanation:
The solubility of gases in water increase with the decrease of the temperature, and vice-versa.
The scape of the gas molecules from solution occurs by the breaks of the intermolecular bonds as a consequence of the increase of the kinetic energy which causes an increase in the motion of the gas molecules in solution.
That is why as the temperature rises the solubility of all gases in water also will decrease.

Answer:Momentum
Explanation:
Product of an object mass and velocity is called Momentum. Basically momentum is the measure of mass in motion . More is the mass more will be the momentum and similar applies for velocity.
For example a bus moving with low velocity can have a same momentum as that of a bullet moving with a very high velocity
Momentum is denoted by Symbol P
The cart comes to rest from 1.3 m/s in a matter of 0.30 s, so it undergoes an acceleration <em>a</em> of
<em>a</em> = (0 - 1.3 m/s) / (0.30 s)
<em>a</em> ≈ -4.33 m/s²
This acceleration is applied by a force of -65 N, i.e. a force of 65 N that opposes the cart's motion downhill. So the cart has a mass <em>m</em> such that
-65 N = <em>m</em> (-4.33 m/s²)
<em>m</em> = 15 kg
Answer:
True
Explanation:
Examples of numerical data are height, weight, age
From the calculations, the speed of sound in this case is 16.9 m/s.
<h3>What is an echo?</h3>
The term echo has to do with the reflection of sound waves. Sound is a mechanical wave.
we know that the speed of sound is obtained from;
V = 2x/t
x = distance covered
t = time taken
V = 2(500)/59
v = 16.9 m/s
The error in the experiment could come from;
- Lack of precise time measurement
- Error can also arise from the environment of the experiment
