Answer:
Hydrogen has only 1 valence electron in its outermost shell.
Explanation:
Answer:
The new temperature will be 2546 K or 2273 °C
Explanation:
Step 1: Data given
The initial temperature = 1000 °C =1273 K
The volume = 20L
The volume increases to 40 L
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 20L
⇒with T1 = the initial temperature = 1273 K
⇒with V2 = the increased volume = 40L
⇒with T2 = the new temperature = TO BE DETERMINED
20L/ 1273 K = 40L / T2
T2 = 40L / (20L/1273K)
T2 = 2546 K
The new temperature will be 2546 K
This is 2546-273 = 2273 °C
Since the volume is doubled, the temperature is doubled as well
Any fire extinguisher should put out a fire, that is unless the extinguisher is old and faulty.
Answer:
P₂ = 220.56KPa
Explanation:
Boyles Law P ∝ 1/V => Inverse relationship => Decreasing Volume => Increasing Pressure.
P₁ = 198 KPa P₂ = ?
V₁ = 15.35 Liters V₂ = 13.78 Liters
P₁V₁ = P₂V₂ => P₂ = P₁(V₁/V₂) = 198KPa(15.35 L/ 13.78L) = 220.6KPa
