<h2>Answer:</h2>

<u>The temperature must be increased in order to evaporate water</u>

<h2>Explanation:</h2>

Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. If the energy of water molecules is increased which means heat is released then the water molecules come to surface of the container and leaves it. These water molecules are called vapors. When water is heated, the molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Answer:

B. use a new pair of gloves for each piece of evidence

Explanation:

When it comes to the basic precautions of handling biological evidence samples, one has to prevent cross contamination. This refers to the<em> transfer of DNA from one evidence to another evidence</em>; thus, it is important for Jane to use a new pair of gloves for each piece of evidence in order to prevent such occurrence.

Wearing of gloves will also <em>prevent Jane's DNA from being implanted into the sample</em>, and it will keep her safe from contracting blood-borne pathogens like those in the saliva, blood or semen.

3CH4 refers to three molecules of a
compound and C3H12 refers to only one
molecule of a compound.
3CH4 and C3H12 are actually different
molecules though they contain the same
number and types of atoms. Recall that both
of them are hydrocarbons hence they
contain only hydrogen and carbon.
3CH4 refers to three molecules of methane
while C3H12 refers to one molecule of
diphenyl methane. Hence 3CH4 refers to
three molecules of a compound and C3H12
refers to only one molecule of a compound.
