Ice is put in a cooler to cool the contents. to speed up the cooling process, the ice can be?

1 answer:

5 0

Crushing increases the ice's surface area. Additionally, cooling from ice happens as a result of convection, which is proportional to area. Thus, breaking up the ice expedites the cooling process.

<h3>What is cooling process?</h3>

When precise and consistent temperature control inside a process is necessary, this sort of cooling is used. Because they can offer cooling capacity independent of variations in the ambient temperature, heat load, and flow needs of the application, chillers are frequently employed to remove heat from a process.

It's important to properly regulate the heat load in many industrial operations. Different components of the whole application might need to be cooled.

Major locations for cooling include:

Direct product cooling

During the molding process, plastic

milling metal products

Willa, the cartoon witch, dusts her crystal ball with her silk scarf, causing it to become charged with 5.0 x 10^ -9 C. Willa th

DIA [1.3K]

Answer:

The distance between the tip of her nose from the center of the crystal ball is 14.3 cm.

Explanation:

Given that,

Charge, $q=5\times 10^{-9}\ C$

The end of her nose experiences an electric field strengths of 2200 N/C

It is required to find the distance between the tip of her nose from the center of the crystal ball. The formula of the electric field is given by :

$E=\dfrac{kq}{r^2}$

r is distance

$r=\sqrt{\dfrac{kq}{E}} \\\\r=\sqrt{\dfrac{9\times 10^9\times 5\times 10^{-9}}{2200}} \\\\r=0.143\ m\\\\r=14.3\ cm$

So, the distance between the tip of her nose from the center of the crystal ball is 14.3 cm.

The synthesis of nitrogen trihydride from nitrogen gas and hydrogen gas is shown by which balanced chemical equation?

Strike441 [17]

Answer:

Option B. N2(g) + 3H2(g) → 2NH3(g)

Explanation:

When nitrogen react with hydrogen, they form a product as shown below:

N2+ H2 → NH3

We need to balance the equation. This is illustrated below:

There are 2 atoms of nitrogen on the left side and 1 atom on the right side. To balance it, put 2 in front of NH3 as shown below:

N2+ H2 → 2NH3

Now, There are a total of 6 atoms of Hydrogen on the right side and 2 atoms on the left side side. This can be balanced by putting 3 in front of H2 as shown below:

N2+ 3H2 → 2NH3

Now we see clearly that the equation is balanced as we have equal numbers of atoms of N and H on both sides of the equation

A moving car has kinetic energy. If it speeds up until it is going four times faster than before, how much kinetic energy does i

Eva8 [605]

<h2>Ratio of final kinetic energy to initial kinetic energy is 16.</h2>

Explanation:

Kinetic energy , KE = 0.5mv²

Here car speeds up to four times the initial speed, we need to find ratio of final kinetic energy to initial kinetic energy.

Final speed = 4 x Initial speed = 4v

Initial KE = 0.5mv²

Final KE = 0.5 x m x (4v)²

Final KE = 16 x 0.5 x m x v²

Final KE = 16 x Initial KE

Ratio of final kinetic energy to initial kinetic energy is 16.
