Explain what happens to the heat that is being added to a substance when the substance is changing phase.

1 answer:

4 0

<span>When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase. For example, ice melts and becomes water; water evaporates and becomes water vapor.These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.</span>

C=h/[M(T2-T1)] solve for T1

vodka [1.7K]

Explanation:

This is expressing as a subject of a formula of a specie.

This equation is used in solving for specific heat capacity of a material;

equation:

c = $\frac{h}{M(T2 - T1)}$

First cross multiply:

c[M(T2 - T1)] = h

Then multiply both sides by $\frac{1}{c }$ :

$\frac{1}{c }$ x c[M(T2 - T1)] = $\frac{1}{c }$ x h

M(T2 - T1) = $\frac{h}{c}$

Multiply both sides by $\frac{1}{M}$

$\frac{1}{M}$ x M(T2 - T1) = $\frac{1}{M} x \frac{h}{c}$

T2 - T1 = $\frac{h}{Mc}$

Now rearrange to produce;

T1 = T2 + $\frac{h}{Mc}$

Can the ratio of hydrogen to oxygen change if a solute is dissolved in the water

coldgirl [10]

Answer:

Water molecules feature the combinations of hydrogen and oxygen atoms in a 2:1 ratio. Since they are present in a fixed ratio of mass, water molecules obey the law of constant proportions. Water is formed when two molecules of the diatomic hydrogen gas, combine with one molecule of the diatomic oxygen gas to produce two molecules of water

Based on this simulation, how does the greenhouse keep plants warm? Use "infrared photons" in your explanation.

frez [133]

Answer: During the day, a typical greenhouse will trap Infrared photons from the sun, which allows the plants inside to stay warm at night. ... The much needed sunlight will still come through but the extra layer of protection will keep your plants safe at night

Explanation: Hope that helps :)

Be sure to answer all parts. Determine the electron-group arrangement, molecular shape, and ideal bond angle for the following m

choli [55]

Answer:

trigonal planar

Explanation:

The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.

There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle. The bond angle is 120 degrees.
