Water among the coast can be several degrees colder in different areas because the water is replenished and being pushed off the coast so these cooler and nutrient-rich waters rise from a depth of 50-300 meters to the surface of the ocean
Answer:
the soup become too salty through the process of osmosis
Answer:
P₂ = 13.9 atm (3 sig. figs.)
Explanation:
The pressure (P), Volume (V) relationship with Temperature (T) & mass (n) held constant is an inverse proportionality. That is Boyles Law ...
P ∝ 1/V => P = k/V => k = P·V
For two pressure-volume conditions, the proportionality constant (k) remains constant where k₁ = k₂ and P₁·V₁ = P₂·V₂ => P₂ = P₁·V₁/V₂
Given:
P₁ = 1.31 atm.
V₁ = 5.51 L
P₂ = ?
V₂ = 0.520 L
V₂ = (1.31 atm)(5.51L)/(0.520L) = 13.88096154 atm (calc. ans.) = 13.9 atm (3 sig. figs.)
Answer: 878 kJ of energy is there in cheeseburger
Explanation:
Given : calorific value of fat = 38kJ/g
calorific value of carbohydrate = 17 kJ/g
calorific value of protein = 17kJ/g
1 g of fat contains energy = 38 kJ
7.0 g of fat contains energy = ![\frac{38}{1}\times 7.0=266 kJ](https://tex.z-dn.net/?f=%5Cfrac%7B38%7D%7B1%7D%5Ctimes%207.0%3D266%20kJ)
1 g of carbohydrate contains energy = 17 kJ
25 g of fat contains energy = ![\frac{17}{1}\times 25=425kJ](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B1%7D%5Ctimes%2025%3D425kJ)
1 g of protein contains energy = 17 kJ
11 g of protein contains energy = ![\frac{17}{1}\times 11=187kJ](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B1%7D%5Ctimes%2011%3D187kJ)
Total energy = (266+425+187) kJ = 878 kJ
