Answer:
V₂ = 379.80 mL
Explanation:
According to <em>Charles' Law,</em> "<em>At constant pressure the volume of given amount of gas is directly proportional to the absolute temperature"</em>. Mathematically it is given as,
V₁ / T₁ = V₂ / T₂ ----- (1)
Data Given:
V₁ = 185 mL
T₁ = -125 °C = 148.15 K ∴ K = °C + 273.15
V₂ = ?
T₂ = 31.0 °C = 304.15 K
Solving eq. 1 for V₂,
V₂ = V₁ × T₂ / T₁
Putting values,
V₂ = 185 mL × 304.15 K / 148.15 K
V₂ = 379.80 mL
Hence, with increase in temperature the volume has also increased.
Answer:
I need the things after "which of the following would occur".
Explanation:
If you were to maintain a constant volume while decreasing pressure, the temperature would also have to decrease. This is Boyle's law.
Answer: Positive
Explanation: Just a guess
Answer:
Explanation:
Lithium, Potassium and Sodium follow each other in that order when it comes to reactivity.
Succinctly put, Lithium is the most reactive. Potassium is more reactive and Sodium is the least reactive.
Also, for Calcium, Strontium and Barium. It is the least reactive in this order.
Strontium, Barium, Calcium
That is, Strontium is more reactive than Barium, which is more reactive than Calcium. Calcium is the least reactive of the 3
