Answer:Volume occupied by the gas at standard pressure is 162.5 L.
Pressure of the gas when it occupies volume of 190 L = 650 mmHg
Volume occupied by the gas when the gas is at standard pressure.
The value of standard pressure = 1 atm = 760 mmHg
According to Boyle's Law: (at constant temperature)
Volume occupied by the gas at standard pressure is 162.5 L.
B. Energy transfer would occur between the copper bars and the surroundings.
In an open system, energy transfer would occur between the copper bars and the surroundings.
There are three types of systems:
If the copper bars were placed in an open system matter and energy will be exchanged with the surrounding.

The correct option is:
Plant uses light energy to produce food molecule during photosynthesis and obtain cellular energy from the bond of these molecule during respiration .
Important points :
Photosynthesis : It is a process in which green <u>plants prepare their food </u>usin<u>g</u> sunlight from CO2 and water .
Here, Food is produced
Respiration : It is a process by which organism obtain energy by breaking the food molecules.
Food molecules are source of energy which contain a large number of bonds. When these bonds break down during respiration , then energy is released .
= food molecule prepared by plants during photosynthesis . It contain many bonds
Hence The bond breaking release energy.
