Answer:

gaseous CO2 bubbles out of the solution

Explanation:

We already know that the dissolution of a gas in water is exothermic. Hence, when the temperature of a solution containing a gas is increased, the solubility of the gas decreases and the gas bubbles out of the solution.

Similarly, the dissolution of KNO3 in water is endothermic. This implies that the solubility of the solid increases with increasing temperature.

Thus the solid becomes more soluble at 75°.

Answer:

Explanation:

1. A measure of how quickly velocity is changing is the acceleration

Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.

It is measured in the unit m/s²

2. Speed in a given direction is the velocity

Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.

When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.

3. Force that resists moving one object against another is the friction

Friction is a force that opposes motion. It prevents a body from moving.

4. Measure of the pull of gravity on an object Weight

Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;

         W = mg

W is the weight, m is the mass and g is the acceleration due to gravity

5 Tendency of an object to resist a change in motion is inertia

Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.

Why can’t an atom lose or gain a proton
Veronika [31]

Explanation:

Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified.
