Answer:3)date geological formations
Explanation:
Absolutely false. If it all have the same average kinetic energy, the substance will not change in state. Hence, it is absolutely false. Go to Google and search for heating curve. When you analyse the curve, the line which is horizontally straight is where the average kinetic energy remains constant. The other lines represent the increase in kinetic energy. So as heat is continued supplying, the substance at some point will increase kinetic energy.
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:
461.54 kg/h
Explanation:
First lets calculate the mass flow of the dry product:
Md=1000 kg/h*(1-0.58) = 420 kg/h
The mass flow of the moist final product is then:
Mm= 420 kg/h /(1-0.22) = 538.46 kg/h
The water to be evaporated is then the difference between the feed and the product.
W= 1000 kg/h - 538.46 kg/h = 461.54 kg/h
