I think in drylands, drylands are particularly affected by desertification.
Answer:
119 kCal per serving.
Explanation:
The heat energy necessary to elevates water's temperature from 23.4°C to 37.9°C can be calculated by the equation below:
Q = mcΔT
Q: heat energy
m: mass in g
c: specific heat capacity in cal/g°C
ΔT = temperature variation in °C
m is the mass of water, considering the density of water to be 1g/mL, 100 mL of water weights 100g. Therefore:
Q = 100 g x 1.00 cal/g°C x (37.9 - 23.4)°C
Q = 1450 cal
1450 cal ____ 0.341 g peanuts
x ____ 28 g peanuts
x = 119061.58 cal
This means that the cal from fat per serving of peanuts is at least 119 kCal.
The graduated cylinder is used to measure the volume of KOH and H2SO4 when accurate volume measurement is not required.
In the laboratory certain graduated apparatus are used to measure liquids. These graduated apparatus used to measure liquids include;
- burette
- pipette
- measuring cylinder
- Erlenmeyer flask
Sometimes, we are not really looking for a strictly accurate volume of liquid and we can use a graduated cylinder to measure the volume of liquid in such cases.
However, when we need to have strictly accurate volume measurement, we need a pipet or a buret.
