Answer:
A condensate is a liquid formed by condensation.
Explanation:
Answer:
a.
Explanation:
Assuming that Liquid X is considered to possess a greater viscosity as well as higher surface tension than liquid Y. Then, liquid X will tend to harbour more pressure inside the liquid.
In addition to that, the greater the surface tension, the greater the force required to expand the liquid's surface area.
This in turn makes the force required to make the loop 5% wider to be greater in FX rather than FY.
Thus, option a is the correct answer.
Answer:
-6.27 kj
Explanation:
Given data:
Energy released = ?
Mass of steam = 15 g
Initial temperature = 100°C
Final temperature = 0°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Specific heat capacity of water is 4.18 j/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 0°C - 100°C = -100°C
Q = 15g × 4.18 j/g.°C × -100°C
Q = -6270 j
J to KJ:
-6270 j/1000 = -6.27 kj
20.82
1 mole = 6.9
6.9 x 3 = 20.823
rounded = 20.82
