Answer:
Explanation:
In the process of convection, first the molecules of substance gets heat and becomes heated. As the molecules heated, their density decreases and hence they rises up. And the molecules which are cooler, they fall and comes in contact of higher temperature and then they rises up. the process repeats itself until the entire liquid heated uniformly.
Double
Explanation:
Since the period T of a pendulum is given by
By increasing the length of the pendulum by 4, the period becomes
You can see that the period doubles when we increase the length by a factor of 4.
Liquids don't have a definite shape, but solids do.
1) temperature
2) pressure
3) concentration
4) surface area
5) the presence of a catalyst
Answer:
36 months or 36,000 miles
Explanation:
CNG cylinder has limited lifespan. Generally lifespan of CNG cylinder is 15 years to 20 years. For safety purpose these cylinder should be inspected timely. Time limit for inspection of CNG cylinder is 36 months or 36,000 miles whichever comes first.
ThusCng cylinders must be inspected at least every 36 months or 36000 miles.
