Reasons why water is a good cooling agent in machines​
Fiesta28 [93]

Answer:

one reason is, Water is a very good liquid for cooling things down, for one thing there is plenty of it and it has also got a high specific heat capacity. This means that it can absorb a large amount of heat energy without getting too hot.


will not heat up or cool down very fast

Water has a high value of latent heat of vapourization so it has cooling properties.
hope this helps you. :)

If the density of a 45.0 cm3 block of wood is 0.65 g/ml what is the mass of the wood?
wlad13 [49]

Answer:

\boxed {\tt mass=29.25 \ grams}

Explanation:

The density formula is mass over volume.

d=\frac{m}{v}

Rearrange the formula for the mass, m. Multiply both sides of the formula by v.

d*v=\frac{m}{v}*v

d*v=m

Mass can be found by multiplying the density and volume. The density is 0.65 grams per milliliter and the volume is 45.0 cubic centimeters.

  • A cubic centimeter is equal to a milliliter.
  • Therefore, 45 cubic centimeters also equals 45 milliliters.

d= 0.65 \ g/mL\\v= 45 \ mL

Substitute the values into the formula.

0.65 \ g/mL * 45 \ mL=m

Multiply. Note the milliliters, or mL will cancel out.

0.65 \ g * 45=m

29.25 \ g=m

The mass of the wood is 29.25 grams.

What property of a substance does its specific heat capacity describe?
Luden [163]

Specific heat describes how much heat a substance takes to raise the temperature. Hence, Option (c) is correct

<h3>What is Specific Heat ?</h3>

Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass.

The specific heat capacity of a material is a physical property.

It is also an example of an extensive property since its value is proportional to the size of the system being examined.

Specific heat describes how much heat a substance takes to raise the temperature. Hence, Option (c) is correct
