b. Describe how the temperature changes within a phase and during a phase change as heat is added to a water sample. (2 points)
Rudik [331]
Hello!

Take for example the heating of water.

When heating liquid water from room temperature (25 °C) to the boiling point (100 °C), adding heat results in a direct increase in the temperature. This kind of heat is called sensible heat, because we can sense the effect of the added energy.

But when you reach 100 °C, there is a phase change from liquid to vapour, and the added heat is used to produce the phase change, and no increase in temperature is observed, only the phase change. This kind of heat is called latent heat. 

Have a nice day!

Taku mixed some water and juice crystals to make a fruit drink.
aliya0001 [1]
This is not a math question but I’ll help. The solute is what you are dissolving something in. The solvent is what is dissolved. So if you are dissolving juice crystals IN water the juice crystals would be the solvent and the water would be the solute

A balanced equation for the dissociation of KI
Ann [662]

Answer:

The balanced equation for the dissociation of KI is

KI →  K⁺ + I⁻

Explanation:

KI is the potassium iodide.

K⁺ comes from the KOH, a strong base, so the cation is the conjugate weak acid and in water it does not react.

I⁻ comes from HI, a strong acid, so the anion is the conjugate weak base and in water it does not react.

K⁻  + H₂O ← KOH + H⁺

I⁻ + H₂O ← HI + OH⁻

That's why the arrow in the reaction is in the opposite direction.
