Answer:
363.6 K
Explanation:
To solve this problem we will use Charles law equation i.e,
V1/T1 = V2/T2
Given data
V1= 350 mL
T1= 45.0 °C
V2= 400.0 mL
T2=?
First of all we will convert the temperature into kelvin because the kelvin is an absolute scale of temperature.
T1= 45.0+ 273.15 = 318.15 K
Now we will put the values in equation
350 mL / 318 K = 400 mL / V2
V2= 400 mL × 318.15 K / 350 mL
V2= 363.6 K
We can see that by increasing the temperature volume of given gas is also increases. we conclude that volume and temperature are directly proportional to each other. It is also confirmed by the Charles law.
“ The volume of given mass of a gas at a constant pressure is directly proportional to the absolute temperature ”
Answer:
I think so this is the answer
Explanation:
Unsustainable way of managing resources means using resources in an unjustifiable manner, using without keeping in the needs for future generations. That is disobeying the principles of sustainability.
For examples release of toxic industrial wastes in rivers and thus, polluting it. Or, Deforestation of land for agricultural or industrial purposes. Thus, reducing the oxygen carrying capacity of Earth.
Answer:
1034 yrs
Explanation:
The equation to use in this question is:
t = -2.303/k log (A/A₀) where
A= present number of disintegrations
A₀ = intial number of disintegrations
k = decay constant
The decay constant we will obtain it from the given hal-life:
k: 0.693/t₁/₂, t₁/₂ = half-life ⇒
k: 0.693 / 5730 y = 1.209 x 10⁻⁴ /y⁻¹
t = - 2.303 / 1.209 x 10⁻⁴ /y⁻¹ x log (13.1/15.3) = 1034 yrs
Answer:
3M
Explanation:
moles ÷ liters = molarity
4.8 ÷ 1.6 = 3M
