____________ heat is the amount of heat required to change the temperature of 1 gram of a substance by 1°C, and it is related to

Jlenok [28]

Answer:

specific heat.

Explanation:

Definition:

The amount of heat required to raise the temperature of one gram of substance by one degree is called specific heat.

Formula:

Q = m. c. ΔT

Q = amount of heat required

m = mass of substance

c = specific heat of substance

ΔT = change in temperature

The substance with greater value of specific heat require more heat to raise the temperature while the substance with lower value will raise its temperature very quickly by absorbing smaller heat.

For example the beach sand gets hot very quickly because of lower specific heat of sand while water is colder than sand because of higher specific heat capacity.

Give the formulas for all of the elements that exist as diatomic molecules under normal conditions. See if you can do this witho

GenaCL600 [577]

Answer:

They are:

H2, N2, O2, F2, Cl2, Br2, and I2.

Note: whether the element At molecule is monoatomic or diatomic is incredibly arguable. While some say it exists as diatomic because it is a halogen like bromine, iodine etc, At is in fact extremely unstable and no one has ever really studied the molecules on it, so, when others say it is monoatomic, this is also based on calculations. But the other 7 elements listen above is for sure diatomic.
