Answer:
Phase C - Liquid State
Phase E - Gaseous State
Explanation:
Usually, in phases of water, we have the following;
When temperature is less than zero, it is said to be in its solid phase as ice.
When temperature is between 0 to 100, we can say it is in the liquid phase as water.
When temperature is above 100°C, It is said to be in the gaseous phase as vapour.
From the diagram;
Phase C is the only liquid state because it falls between temperature of 0°C and 100°
Also, only phase E is in the gaseous phase because the temperature is above 100°C.
The process of watering the crops is called irrigation.
Any two methods of irrigation are:
<h3>(i) Sprinkler system:</h3>
This system is used on the uneven land where less water is available. The perpendicular pipes, having rotating nozzles on top, are joined to the main pipeline at regular intervals. Water is allowed to flow through main pipe under pressure, which escapes from the rotating nozzles. In this way water gets sprinkled on the crop.
<h3> (ii) Drip irrigation:</h3>
This system is used to save water as it allows the water to flow drop by drop at the roots of the plants. It is the best technique for watering fruit plants, gardens and trees. Water is not wasted at all.
Answer:
Option D
Explanation:
analyzing cells is something I'm doing in science class right now!
Hope this helped, have a nice day! :)
Consisting of a single cell.
Q = 5637 J
C =4.814 J/KgºC
Temperature : 45.5ºC - 20.9º C = 24.6ºC
Q = m x C x T
5637 = m x 4.814 x 24.6
5637 = m x 118.4244
m = 5637 / 118.4244
m = 47.60 g
hope this helps!
