Answer:

Perform research to see if other polar molecules have high specific heat

Explanation:

The specific heat of a substance is the amount of heat required to raise the temperature of a unit mass of the substance by 1°C.

In this question, the student is trying to establish a relationship between polarity and specific heat of substances. This claim can be tested by performing a research to see if other polar molecules have high specific heat.

If the research shows that a large number of other polar molecules have high specific heat, then the claim is confirmed to be true.

Lelechka [254]

Answer:

$^{32}_{15}P$

Explanation:

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

However, when we talk about the atomic number of the ion, it is not equal to the number of electrons as electron can be gained or loosed.

This is why, more appropriately, the number of the protons which are present in the nucleus of the atom is called the atomic number.

Thus, atomic number of phosphorus = 15

Mass number is the number of the entities present in the nucleus which is the equal to the sum of the number of protons and electrons.

Given, Mass number = 32

Thus, the symbol of the isotope is:-

$^{32}_{15}P$

How does your body obtain energy from the carbohydrates you eat?

Komok [63]

Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
