Answer:
The mass of water that will evaporate 2.857 kg.
Explanation:
Given;
temperature of the water, T = 100 c
rate of heat transfer, H = 2 kW = 2000 w
time, t = 10 min = 10 min x 60s = 600s
heat capacity of water is given by;
Q = McΔT
Where;
Q is the quantity of heat transfer to the pan = P x t = 2000 x 600 = 1200000 J.
c is specific heat capacity of water = 4200 J/kg.°C
m = (Q) / (cΔT)
m = (1200000) (4200 x 100)
m = 2.857 kg
Therefore, the mass of water that will evaporate 2.857 kg.
Answer:
5 km
Explanation:
displacement is the straight line distance from a particular point. since north and south are in opposite directions, it means that he has taken a u-turn
thus, 10 - 5 = 5km displacement
Let's mention 2 examples of a mixture:
1) blood- blood is a mixture of blood plasma and blood cells. Blood is very important to many forms of life, including humans. It's therefore essential to living things!
2) ocean water! it's also a mixture and it covers a great portion of the Earth.
Answer:
11970 pa
Explanation:
A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals so if 1 mmHg is 133 pa 90mmHg is 11970 aprox
