Answer:
different sample have different properties is not a characteristics of a compound ,
Explanation:
because compound will always same properties no matter how quantity is
Answer:
The atmospheric pressure and boiling point are directly proportional
Increasing atmospheric pressure increases the boiling point also
Explanation:
The atmosphere contain molecules that are in constant motion. They exert a downward force on a liquid’s surface. The higher the air pressure, the harder it is for the liquid to evaporate. Therefore, the boiling point of a solvent or liquid is affected by the atmospheric pressure and boiling point is raised.
A liquid in a high pressure environment boils at a higher temperature.
When placed in a lower pressure environment it boils at a lower temperature.
The increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.
<h3>How to calculate temperature change?</h3>
The temperature change of a substance can be calculated using the following formula:
Q = m × c × ∆T
Where;
- Q = quantity of heat absorbed or released
- m = mass of substance
- c = specific heat capacity
- ∆T = change in temperature
5000 = 225 × 0.385 × ∆T
5000 = 86.63∆T
∆T = 5000/86.63
∆T = 57.72°C
Therefore, the increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.
