Answer:
The smell from the cake leaves the room at high velocities because of diffusion.
Kinetic theory:
The kinetic theory applies to gases and describes their random movement and collisions in the whole volume that they are allowed to fill. This movement depends on factors like temperature and pressure.
Coffee and bacon particles will exist in the air in gaseous form. They will be colliding with each other, with all the other air particles and with the room walls to eventually disperse evenly in the whole room. They will be detected when coming into contact with olfactory receptors in the nose. They will reach the nose at the same temperature and there are equal amounts of particles of each.
Yes a recessive allele can hide their trait if a dominant allele is present.
Answer:
The original concentration is "35 mg/ml".
Explanation:
According to the question,
The solution is diluted,
= 1:50
The initial volume,
V1 = 1 ml
Final concentration,
= 0.07 mg
then,
The final volume,
V2 = 500 ml
As we know,
⇒ 
or,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
Answer:
A large plateau forms in the interior of a continental plate when a large section of the plate rises evenly due to an even expansion of the underlying mantle. B.
Explanation:
The absolute temperature is the lowest possible temperature in the universe. At this temperature, all atoms become motionless and cease to move.
The value of the absolute zero is pegged at -273.16°C.
- It is the lowest limit of the coldness of a body.
- Nothing can be colder than a body at absolute temperature.
- Many researches are underway to take advantage of this temperature value for scientific purpose.
- Thermodynamically, all process stops at this temperature.
- When a body is brought close a body at absolute zero, it can suffer cryogenic burn due to heat transfer.
