Answer:
The final volume of the sample of gas = 0.000151
Explanation:
Initial volume = 200 ml = 0.0002
Initial temperature = 296 K
Initial pressure = 101.3 K pa
Final temperature = 336 K
Final pressure = K pa
Relation between P , V & T is given by
Put all the values in the above equation we get
= 0.000151
This is the final volume of the sample of gas.
initial condition : Vi = 4.700 L , Ti = 71.0ºC +273 => 344 K
final condition : Vf = 3.300 L , Tf = ?
Pressure is constant:
According to charle's law , volume is directly proportional to temperature at constant pressure !
Hence Vi / Ti = Vf / Tf
4.700 L / 344 K = 3.300 L / Tf
Tf = 3.300 L * 344 K / 4.700 L
Tf = 1135200 / 4.700
Tf = 241.53 K
Tf = 241.53 - 273
Tf = -31.47ºC
Answer:
The correct answer to you your question is Potassium
Explanation:
Potassium is the most reactive
Kelvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops - all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius.
