Answer:
7.462
Explanation:
Well, every time that the tempurature is increased, the atmspheric pressure is increased by 0.574%. This would then mean that you would have 0.574 times
13. That would then equal 7.462. I hope this helps.
Answer:
Explanation:
<u>Relation between grams of Carbon and moles</u> :
<u>Multiply both sides by 2</u> :
⇒ 1 x 2 moles = 12 x 2 g
⇒ 2 moles = 24 g
Solute is the term used for a substance being dissolved in a solution.
Different elements produce different colors of light when heated because the electrons in these elements have different permissible energy levels. When an element is heated, the electrons inside it become excited and move to an higher energy level from the ground state. When the electrons drop from this higher energy level, they typically emit energy quantum, the color of the light that is observed at this stage depends on difference that exist in the two energy levels.<span />

Answer:</h3>
Change in temperature = 2.03°C, the temperature is increasing
<h3>
Explanation:</h3>
- To calculate the quantity of heat absorbed or released by a substance we multiply mass of the substance by it's specific heat capacity and the temperature change.
- Therefore, Quantity of heat, Q = mass × specific heat × change in temperature
In this case;
Mass of water = 30.0 g
Quantity of heat absorbed = 255 J
Specific heat capacity of water = 4.186 J/g°C
Rearranging the formula, Δt = Q ÷ mc
Δt = 255 J ÷ (4.186 J/g°C×30.0 g )
= 2.03 °C
The temperature change is 2.03°C, the temperature is therefore increasing.
