Asample of diborane gas a substance that bursts into flame when exposed to air, has a pressure of 345 tore at a temperature of -15c and a volume of 3.48 l. if conditions are changed so that the temperature is 36c and the pressure is 468 tore, what will be the volume of the sample?

3.072 L

We are given;

But, K = °C + 273

          = -15°C + 273

          = 258 K

                                   = 36 °C + 273

                                   = 309 K

We are required to calculate the new volume, V₂

P₁V₁/T₁ = P₂V₂/T₂

V₂ =(P₁V₁T₂) ÷ (T₁P₂)

   = (345 torr × 3.48 L × 309 K) ÷ (258 K × 468 torr)

   = 3.072 L

Therefore, the new volume of the sample is 3.072 L

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
