E= (231 aj/pm) (-2)(2)/77+140 Pm
E= 231 aj (-4)/217
E= -868 aj/ 217
E= -4aj
Answer:
RH = 20%
Explanation:
Data given:
water pressure at 0°C = 4.85 g/m³
Actual water vapor density = 0.97 g/m³
Relative humidity (RH) = ?
Solution:
Formula used
Relative humidity (RH) = 
x 100%
As we know that at 0°C water vapor have 4.85 g/m³ saturated vapor density.
So,
put values in the above formula
Relative humidity (RH) = 0.97 g/m³ / 4.85 g/m³ x 100%
Relative humidity (RH) = 0.2 x 100%
Relative humidity (RH) = 20%
So,
Relative humidity (RH) = 20%
Answer:
c. glycogen - is a polyssaccharide composed from sub-units of glucose
Explanation:
a. lactase - this is an enzyme compouse of many aminoacids and it has a complex structure
lactose - is a disaccharide composed from sub-units of galactose and glucose
b. glucose - is a monosaccharide
c. glycogen - is a polyssaccharide composed from sub-units of glucose
d. sucrose - a disaccharide composed from sub-units of glucose and fructose
e. triacylglycerol - is formed by condensation of glycerol with three molecules of fatty acids
True
Pressure is the force per unit area on an object. The force in the case of air pressure is the weight of the air molecules; therefore, the air pressure is essentially due to gravity pulling down air molecules.
