A sample of nitrogen in a rigid container that is originally at 25.0°C and 98.0 kpa is heated until the pressure is 177 kpa. What is the final temp in Kelvin, in degrees celsius

The final temp : 538.2 K = 265.2 °C

Given

Temperature : 25 + 273 = 298 K

Initial Pressure = 98 kPa

Final pressure = 177 kPa

Required

The final temp

Solution

Gay Lussac's Law  

When the volume is not changed, the gas pressure is proportional to its absolute temperature  

Input the value :

T₂=(P₂.T₁)/P₁

T₂=(177 x 298)/98

T₂=538.2 K

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
