Explain how there can be more heat energy in an iceburg than in a pot of boiling water
vlada-n [284]

Heat energy is the amount of heat there is in a substance. This may be cold heat or warm heat. Temperature is how hot or cold a substance is. So because there is a higher volume of heat in the iceberg, we say it has more heat energy.

A 0.080 kg robin sits on a perch 6.0 meters above the ground. What is the potential energy of the robin
Nesterboy [21]

Answer:

4.704J

Explanation:

The following data were obtained from the question:

m = 0.080kg

h = 6.0m

g = 9.8m/s^2

P.E =?

P.E = mgh

P.E = 0.08 x 9.8 x 6

P.E = 4.704J

Therefore, the potential energy of the robin is 4.704J

Akimi4 [234]

Answer:

Molality, Solvent, Solute, Mole fraction, Molarity.

Explanation:

The expression of concentration that provides the moles of solute per kilograms of solvent is Molality.  This in the only expression referred to the solvent.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solvent is water.  When water is present, it is usually considered the solvent.

A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the Solute is sodium chloride.  There can be 1 or more solutes in a solution.

If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the Mole fraction of sodium chloride would be 0.25.  The mole fraction is equal to the moles of a substance divided by the total number of moles.

A way to express concentration that provides the moles of solute per liter of solution is Molarity.
