Answer is: a) I only.
Above critical temperature of CO₂, a gas cannot be liquefied no matter how much pressure is applied. Temperature and pressure above its critical point is called supercritical fluid and this is <span>intermediate between gaseous and liquid states.</span>
It gets all the energy from food food is every important
Answer:
Explanation:
When gas changes to liquid, it releases the thermal energy that has been absorbed before to become gas which does not alter the temperature at all. A reduction in energy changes the arrangement of particle. There spacing between the particles also increases but not as in a gaseous state and so does the kinetic energy. The particles now are now arranged in irregular pattern.
Le us discuss how we should approach this problem. We know that there are two states. The first state is when P₁ = 1 bar and V₁ = 1.59 L. The second state is when P₂ = 80 bar. We are asked to find V₂. At constant temperature, we use Boyle's Law.
P₁V₁ = P₂V₂
V₂ = P₁V₁/P₂ = (1 bar)(1.59 L)/(80 bar)
<em>V₂ = 0.02 L</em>
