The correct answer is 1000 Kg/M³
Density of water =1-g/cm3.
We know 1- g= 10^-³ Kg
cm³ =(10^-2)³= 10^-6
Substituting we get
Density of water
= 1 x (1x10^-³)/10^-6 Kg/M³
= 1x10^3 = 1000 Kg/M³
<h3>
what is density?</h3>
Density is the mass of a material substance per unit volume. Density is defined as d = M/V, where d represents density, M is mass, and V is volume. Density is generally measured in grammes per cubic centimetre. Water, for example, has a density of 1 gramme per cubic centimetre, but Earth has a density of 5.51 grammes per cubic centimetre. Density is sometimes measured in kilos per cubic metre (in metre-kilogram-second or SI units). The density of air, for example, is 1.2 kilogrammes per cubic metre. Textbooks and handbooks list the densities of common solids, liquids, and gases.

Answer:
<h3>The answer is 200 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass = 150 g
density = 0.75 g/cm³
We have

We have the final answer as
<h3>200 cm³</h3>

The answer for Plato will be letter A
Answer:
68000J/kg
Explanation:
Given parameters:
Mass of the substance = 0.5kg
Quantity of heat transferred to the body = 34000J
Unknown:
Specific latent heat of fusion = ?
Solution:
The specific latent heat is usually involve in phase changes;
H = mL
H is the quantity of heat supplied
m is the mass
L is the specific latent heat
Insert the parameters and solve;
34000 = 0.5 x L
L =
= 68000J/kg
