Answer: For the given reaction an increase in the forward reaction rate due to increase in the number of effective collisions.
Explanation:
According to the rate law, rate of a reaction depends on the concentration of its reactants. So, more is the number of reactants then more will be the number of collisions taking place.
As a result, more will be the amount of product formed. For example, in the reaction
an increase in
means an increase in the number of reactants.
Hence, more is the number of collisions taking place leading to more amount of formation of products.
Thus, we can conclude that for the given reaction an increase in the forward reaction rate due to increase in the number of effective collisions.
An incandescent bulb becomes hotter than a fluorescent bulb when turned on because in a regular incandescent bulb, there is tungsten wire where electricity is converts into heat. A regular incandescent light bulb requires 4 times more energy than a fluorescent bulb in order to produce the same amount of light. The conversion is such that for a 75-watt bulb, temperature get raised to approximately 2000 K. For such a high temperature, the radiating energy from the wire have some visible light. In such bulbs, 90% of the electricity get consumed in producing heat and only 10% produces light thus, they are not much efficient source of light.
On the other hand, fluorescent bulbs produce light with less amount of heat. In them, 40% of electricity is consumed in producing light and 60% in heat which is very less as compared to heat produced by a incandescent bulb. This is because when it get turned on, mercury atoms inside the bulb collides with electrons and produce UV light which is then converted into visible light using thin layer of phosphor power present inside the bulb. This produces low amount of heat thus, the bulb stays cooler, the bigger size of bulb also helps in dispersing heat.
Therefore, a fluorescent light bulb is not as hot as an incandescent light bulb.
Answer:
ON
Explanation:
Frictional force is a force that opposes the motion of body. It is because of friction that motion can be controlled and even walking is made possible.
Now, on a frictionless surface, there is no opposition to motion. Therefore, to keep the body moving there is no force required.
- If surface lacks friction, motion will continue perpetually without any hinderance.
Answer:
1. Animal cells are eukaryotic
2. All live things are made up of cells (I think)
3. Cells are the basic unit of all living things
Explanation:
Number 2 is probably wrong because I can't see the diagram but, all living things ARE actually made up of cells
The temperature of the nitrogen gas is 292.5 K.
<u>Explanation:</u>
Given that
Moles of Nitrogen, n = 5 mol
Volume, V = 30 L
Pressure, P = 4 atm
Gas Constant, R = 0.08205 L atm mol⁻¹ K⁻¹
Temperature = ? K
We have to use the ideal gas equation,
PV = nRT
by rearranging the equation, so that the equation becomes,
T = 
Plugin the above values, we will get,
T = 
= 292.5 K
So the temperature of the nitrogen gas is 292.5 K.
