Answer: Option (C) is the correct answer.
Explanation:
Movement of particles in a substance is responsible for change in state of the substance or matter.
This means that more is the motion of particles more will be their kinetic energy.
Also, kinetic energy is directly proportional to temperature.
K.E = 
So, less is the temperature of an object or substance less will be be the motion of its particles. Therefore, molecules will come closer to each other and state of substance will change from liquid to solid.
Thus, we can conclude that the motion of the molecules would decrease at a molecular level if a liquid is placed in cool conditions.

See details below
Explanation:
The balanced reaction equation is given below:

Mole fraction of CO2 to H20
= 8/10 = 
Mole ratio of C4H10 to CO2 is 2:8 = 1:4
1 mole of n-butane - 38.12 g
4 moles - ?
= 152.48g fuel consumed.
(i) We start by calculating the mass of sugar in the solution:
mass of sugar = concentration × solution mass
mass of sugar = 2.5/100 × 500 = 12.5 g
Then now we can calculate the amount of water:
solution mass = mass of sugar + mass of water
mass of water = solution mass - mass of sugar
mass of water = 500 - 12.5 = 487.5 g
(ii) We use the following reasoning:
If 500 g solution contains 12.5 g sugar
Then X g solution contains 75 g sugar
X=(500×75)/12.5 = 3000 g solution
Now to get the amount of solution in liters we use density (we assume that is equal to 1):
Density = mass / volume
Volume = mass / density
Volume = 3000 / 1 = 3000 liters of sugar solution
Answer:
0.2 is conpound Co2 STP.
Explanation:
on combustion of 0.2 gm of organic compound gave 0.147g of CO2, 0.12g of H2O and 74.6 ml of nitrogen gas at STP. Find emperical formula of compound.?
Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.
Explanation:
The correct option of all is that transverse waves have motion perpendicular to velocity while longitudinal waves have motion parallel to velocity.
A wave is a disturbance that transmits energy from one point to another. There several types of waves like sound, electromagnetic , ocean waves etc.
- Waves can be classified as either longitudinal or transverse waves based on the direction through which they are propagated.
- Longitudinal waves are waves propagated parallel to the source of velocity.
- An example is sound waves and seismic p-waves.
- They have series of rarefaction and compression along their path.
- Transverse waves are propagated perpendicular to their source.
- An example is electromagnetic waves in which electrical and magnetic fields vibrates perpendicularly.
