Answer:
5.6L
Explanation:
Given parameters:
number of moles = 0.25mol
pressure on gas = 1atm
temperature = 273K
Gas constant R = 0.0821Latm/molK
Unknown:
Volume of gas = ?
Solution:
Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.
It is mathematically expressed as;
PV = nRT
where P is the pressure
V is the volume
R is the gas constant
T is the temperature
n is the number of moles
All the parameters are in the appropriate units and we simply solve for the volume of the gas;
1 x V = 0.25 x 0.0821 x 273
V = 5.6L

Heart disease affects the cardiovascular system by plaque building up on the artery walls narrowing them making it harder for blood to flow through which could lead to heart attack or probably stroke if the plaque blocks it entirely or maybe almost entirely.
Heart disease may also affect our nervous system for there is higher risk to stroke and it is due to limited flow of blood to the brain and may lead to heart failure which may happen with heart disease that puts the stress on the brain and nerves.
The digestive system is affected by heart disease that causes the system to not get the right amount of oxygen and the nutrients that it needs from the blood.
