, how does temperature and amount of water affect thermal energy? explain your answer in 5 sentences.

8 0

Heat is occasionally called a process quantity, for the reason that it is defined in the background of a process by which energy can be transported. The consequence of heat on water hinge on whether the energy is touching into the water (endothermic) or touching out of the water (exothermic). When water molecules get energy, the average speed of the molecules rises; this is computed as a temperature change if enough energy is gained.

307.0 mL of air is at 0 C. What is the volume (L) at 273 C

IgorC [24]

Use Charle's Law because we are dealing with volume and temperature.

$\frac{v}{t} =\frac{v}{t}$

v₁= 3017.0 ml

t₂ = 0

v₂= ???

t₂= 273°C

Change all mL's to L because the question says "What is the volume (L)...".

3017.0 mL = 3.017 L

Change the temperature into Kelvins: Kelvin = Celsius + 273.15

0°C = 273.15 K

273°C = 546.15 K

Now you can plug it in the formula:

$\frac{3.017}{273.15} = \frac{v}{546.15}$

Then, do cross multiplication.

(3.017) (546.15) = (273.15) v₂

1,647.73 = (273.15 K) v₂

Divide 273.15 on both sides

6.0296 L= V₂

If a reaction solution at equilibrium is cooled down and the color shift moves toward the reactants, is the reaction endothermic

sertanlavr [38]

Answer:

Endothermic reaction.

Explanation:

Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.

For endothermic reaction, it can be represented as:

Reactants + heat ↔ Products.

As the temperature cooled, it is like that decreasing the concentration of reactants side, that shifts the reaction towards the lift side (reactants side) to attain the equilibrium again.

So, the reaction is an endothermic reaction.
