Answer:
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. ... For example, the density of air is 1.2 kilograms per cubic metre.
We should set our possible combinations to determine the phenotypes.
BB= bushy eyebrows
Bb= bushy eyebrows
bb= no bushy eyebrows
BB x bb
According to the <span>Punnett </span>square that I attached as a pic. There is a 100 percent of all their children to have bushy eyebrows since all will be Bb
Antifreeze is an additive in water-based liquid to lower down the freezing point of such liquid. It is used to make use of the colligative properties of solutions specifically freezing-point depression for cold climate and boiling-point elevation to allow higher coolant temperature.
I'm not sure, but I think its Vandium.
Answer:
(a). With fewer molecules in the container, the molecules have lower average speeds.
(b). With fewer molecules per unit volume, the molecules hit the walls of the container less often.
(c). With lower average speeds, on average the molecules hit the walls of the container with less force.
Explanation:
Ideal gas law is given as;
PV = nRT
Where;
P is the pressure of the gas
V is the volume of the gas
n is the number of moles of the gas (amount of gas )
R is ideal gas constant
T is the temperature of the gas
If the amount of gas is decreased, while the volume and temperature are held constant, the pressure will decrease because number of gas moles per unit volume will be reduced, causing the entropy of the gas to be reduced since entropy decreases with decrease in gas molecules.
As the entropy of the gas molecules reduce, the average speed of the gas molecules will be reduced as well, this will cause fewer collision of the gas molecules with the walls of the container ( i.e on average the gas molecules hit the walls of the container with less force since force is directly proportional to speed, and less force implies less pressure since the contact surface is constant).
Choosing all that apply:
- (a). With fewer molecules in the container, the molecules have lower average speeds.
- (b). With fewer molecules per unit volume, the molecules hit the walls of the container less often.
- (c) . With lower average speeds, on average the molecules hit the walls of the container with less force.
