Scientists calculate the pressure within a gas by using the following equation: $$ P=\frac{N \times k \times T}{V} $$ In the equation: \(P\) is the pressure of the gas; \(N\) is the number of particles in the gas; \(k\) is a constant; \(T\) is the temperature of the gas; \(V\) is the volume of the gas. If the number of particles in the gas decreases, which of the following changes will result in an increase in the pressure of the gas? A. decreasing both the volume and the temperature of the gas B. increasing both the volume and the temperature of the gas C. increasing the volume and decreasing the temperature of the gas D. decreasing the volume and increasing the temperature of the gas
