Answer:
E and B
Explanation:
the warmer the weather the faster it will decompose, this why is why sometimes bodies last longer frozen, or in cool temperatures.
that statement takes a out.
An illness shouldn't effect a decomposing body
Weight also shouldn't effect a decomposing body
Being buried can make bodies decompose fast because of all the bugs and other animals that will get down there and decompose it faster
Answer: B,E
Answer:
If the volume of the container is decreased by a factor of 2 the pressure is is increased by the same factor to 1664 torr.
Explanation:
Here we have Boyle's law which states that, at constant temperature, the volume of a given mass of gas is inversely proportional to its pressure
V ∝ 1/P or V₁·P₁ = V₂·P₂
Where:
V₁ = Initial volume
V₂ = Final volume = V₁/2
P₁ = Initial pressure = 832 torr
P₂ = Final pressure = Required
From V₁·P₁ = V₂·P₂ we have,
P₂ = V₁·P₁/V₂ = V₁·P₁/(V₁/2)
P₂ = 2·V₁·P₁/V₁ = 2·P₁ = 2× 832 torr = 1664 torr
Explanation:
Cholesterol concentration = 27 mg/ 232 mL
Change unit mg/ml to kg/m³
1 kg = 1000 g
1 g = 1000 mg
1 kg = 1000000 mg
1 kg = 10⁶ mg
10⁶ mg = 1 kg
1 mg = 10^-6 kg
m³ = 1000 L
1 L = 1000 mL
m³ = 1000000 mL
m³ = 10⁶ mL
10⁶ mL = m³
1 mL = 10^-6 m³
Cholesterol concentration = 27 mg/ 232 mL
27 × 10^-6 kg/ 232 × 10^-6 m³
= 27/232 kg/m³
42.34 g of water could be warmed from 21.4°C to 43.4°C by the pellet dropped inside it
Heat loss by the pellet is equal to the Heat gained by the water.
….(1)
where, 
is the heat gained by water
is the heat loss by pellet
= mCΔT
where m = mass of water
C = specific heat capacity of water = 4.184 J/g-°C
ΔT = Increase in temperature
ΔT for water = 43.4 - 21.4 = 22°C
= m × 4.184 × 22 …. (2)
Now
= 
×ΔT
where = Heat capacity of pellet = 56J/°C
Δ T for pellet = 43.4 - 113 =- 69.6°C
= 56 × -69.6 = -3897.6 J
From equation (1) and (2)
-m× 4.184 × 22 =-3897.6
m= 42.34 g
Hence, 42.34 g of water could be warmed from 21.4 degrees Celsius to 43.4 degrees Celsius by the pellet dropped inside it.
