what is it?
Answers
The gas that Dr. Walter Snelling discovered in 1911 that becomes a liquid under moderate pressure and acts as an energy source is propane.
Properties of PropanePropane is a gas at room temperature and it was isolated by Dr. Walter Snelling around 1911 in the process of trying to stabilize gasoline.
At cold temperatures or moderate pressure, propane becomes a liquid.
Propane has been and is still being used as an energy source in cooking, powering vehicles, and cutting metals in industrial welding.

How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour
Answers
Answer:
The correct answer would be - 25 times more.
Explanation:
The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.
Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -
= (80/16)^2
= (5)^2
= 25 times more.
Thus, the correct answer would be - 25 times.
The correct answer would be - 25 times more.

What is the solute potential (ΨS ) of a 3.0 M NaCL solution at 27°C under standard atmospheric conditions?
Answers
Answer:
149.58 bars
Explanation:
The solute potential (ΨS) of a solution is given by:
ΨS = iCRT
Where i = ionization constant of the solution, C = molar concentration of the solution, R = pressure constant =0.0831 liter bars/mole-K, and T = temperature in Kelvin.
NaCl dissociates in water to give Na and Cl ions, hence, i = 2
T = 27 + 273 = 300 Kelvin
C = 3.0 M
ΨS = 2 x 3 x 0.0831 x 300
= 149.58 bars.

In which case one can reject the delivery?When receiving raw shell eggs you must reject the delivery if they don't conform to the standard range of conditions. Raw egg shells at temperature of 45°F or below should be rejected during delivery as a result of the possibility of the presence of pathogens on them which exposes individuals to diseases.
The common pathogen found in eggs is Salmonella which causes typhoid. All egg shells should be treated at higher temperatures in order to destroy them.
