Answer:
Rest. Avoid activities that cause pain, swelling or discomfort.
Ice. Use an ice pack or ice slush bath immediately for 15 to 20 minutes and repeat every two to three hours while you're awake.
Compression. To help stop swelling, compress the ankle with an elastic bandage until the swelling stops.
Elevation.
Answer:
The value of entropy change for the process 
Explanation:
Mass of the ideal gas = 0.0027 kilo mol
Initial volume 
= 4 L
Final volume 
= 6 L
Gas constant for this ideal gas ( R ) = 
Where 
= Universal gas constant = 8.314 
⇒ Gas constant R = 8.314 × 0.0027 = 0.0224 
Entropy change at constant temperature is given by,
Put all the values in above formula we get,
![dS = 0.0224 log _{e} [\frac{6}{4}]](https://tex.z-dn.net/?f=dS%20%3D%200.0224%20%20log%20_%7Be%7D%20%5B%5Cfrac%7B6%7D%7B4%7D%5D)
This is the value of entropy change for the process.
Answer:
Liquid to Gas
Explanation:
The particles need energy to rise and over come the attractions between them as the liquid gets warmer more particles have sufficient, energy to escape from liquid. eventually even particles in the middle of the liquid form bubbles of gas in the liquid At this point the liquid is boiliing and turning into gas.
