Answer:
4.7 m³
Explanation:
We'll use the gas law P1 • V1 / T1 = P2 • V2 / T2
* Givens :
P1 = 101 kPa , V1 = 2 m³ , T1 = 300.15 K , P2 = 40 kPa , T2 = 283.15 K
( We must always convert the temperature unit to Kelvin "K")
* What we want to find :
V2 = ?
* Solution :
101 × 2 / 300.15 = 40 × V2 / 283.15
V2 × 40 / 283.15 ≈ 0.67
V2 = 0.67 × 283.15 / 40
V2 ≈ 4.7 m³
B) Weather changes day to day, while climate changes region to region.
Climate is the weather in a certain area. It's usually the average weather over a long period of time
Weather is in shorter terms then climate

Answer:
The breaking in <em>molecular</em> bonds in food releases energy for your body to use.
Eras and then smaller periods based on geologic and biologic events that occurred during those times. According to geological time scale, there are six eras from the beginning some periods of few eras & then period is classified into smaller units called "epoch"
In short, Your Answer would be Option B
Hope this helps!
The relationship between mass m, volume V and density d is:
The silver has density
, and the mass of the piece of silver is
. Therefore we can calculate its volume using the previous formula:
