When you set a pot of tap water on the stove to boil, you'll often see bubbles start to form well before boiling temperature is

ever reached. Explain this observation.
1. These initial bubbles are the gases that were dissolved in the water coming out of solution. The solubility of gases in water decreases with increasing temperature.
2. They are very minute pockets of water in the gaseous phase. When they get large enough, the water will boil as this gas escapes.
3. These bubbles are formed as the surrounding gases from the air dissolve into the water as it is heated.
4. These are dissolved salts heating up and escaping from the water.

Answer:1

Explanation:

When we boil the water, initially small bubbles started forming at the bottom of the vessel. These bubbles are air which enables the aquatic organisms to survive inside the water.  

The solubility of gas started decreases as we increase the temperature, therefore, more and more bubbles formed. Around 373 K water started boiling and vapor started forming inside the water. At this Point water and its vapor is in Equilibrium and every molecule has the same tendency to form a bubble. So there is more and more tendency to form bubbles.

A Hooke's law spring is compressed 12.0 cm from equilibrium, and the potential energy stored is 72.0 J. What compression (as mea
Anuta_ua [19.1K]

Answer:14.14 cm

Explanation:

Given

Spring Compression x=12 cm

Potential energy Stored in spring=72 J

Suppose k is the spring constant of spring

Potential Energy of spring is given by =\frac{kx^2}{2}

\frac{k(0.12)^2}{2}=72

k(0.12)^2=144

k=10,000 N/m

k=10 kN/m

for 100 J energy

\frac{k(x_0)^2}{2}=100

10\times 10^3\cdot (x_0)^2=200

(x_0)^2=2\times 10^{-2}

x_0=0.1414

x_0=14.14 cm

If C is 1kg and D is 100kg, and the initial velocities of both balls are 5m/s, how would the magnitude of the forces exerted by
kupik [55]

Answer:

Explanation:

The forces exerted by each mass is best understood in terms of their momentum.

Momentum is a sort of compelling force or impulse. It is given as:

                  Momentum  =  mass x velocity

Let us consider the momentum of the balls;

Substance C;

    Mass  = 1kg

     Velocity  = 5m/s

    Momentum of C = 1 x 5  = 5kgm/s

Substance D:

      Mass  = 100kg

      Velocity  = 5m/s

     Momentum of D  = 100kg x 5m/s  = 500kgm/s

Body D has a higher momentum compared to Body C. This suggests that body D will exert a higher force than C when they collide.

The higher the momentum, the more the force of impact it has.
