Gay lussacs law graph

B. How did tripling the pressure change the gas volume? At 0°C, the temperature in Kelvins is 273 K.

P= k (273) ≠ 0. 3. In Gay-Lussac’s experiments, he had a rigid container with a set volume.

Gay-Lussac’s Law Example Problems

Problem: You are trying to dispose of an aerosol container that has a pressure of at .

Plot a point every 50 degrees to create a graph showing the relationship between temperature and volume. As temperature increases, pressure increases as well. Record the pressure and volume of the gas for each added mass. T. Click the camera icon to take a snapshot. Collect data: Select the TABLE tab. 4. 8. A. When the volume is held constant, how does the pressure change as temperature increases?

Mathematically represented as follows:

P α T

Converting proportionality into equality gives us:

P = k T

k = P/T

• Where P = pressure, T = temperature and k = proportionality constant

If the temperature of a gaseous system is changed from T₁ to T₂, its pressure changes from P₁ to P₂ and the relationship between the two variables can be expressed as per Gay-Lussac’s law:

P₁/T₁ = k……Equation (i)

P₂/T₂ = k ….Equation (ii)

As the value of k stays unchanged so, the combined equation becomes:

P₁/T₁ = P₂/T₂

What do the components of P₁/T₁ = P₂/T₂ represent?

(Activity A continued on next page) 2018 Divided by 4 Activity A (continued from previous page) 6. B. How does the change in temperature affect the volume of the container?

State whether doubling the temperature (in Kelvin) doubles the pressure for a fixed volume of gas. 1. Both laws involve proportions and multiplication, however one is directly correlated and the other is indirectly correlated. 4.
