Charles’s Law describes the direct relationship between the volume and temperature of a gas at constant pressure‚ expressed as V1/T1 = V2/T2. This formula‚ derived from Jacques Charles’s experiments‚ shows that when temperature increases‚ volume proportionally increases‚ and vice versa. It is crucial to use temperatures in Kelvin to avoid errors. For example‚ if a gas occupies 2 liters at 300 K‚ and the temperature rises to 350 K‚ the new volume can be calculated as V2 = (V1 × T2) / T1‚ resulting in approximately 2.33 liters. This law assumes ideal gas behavior and constant pressure‚ making it a foundational concept in understanding gas properties and behavior under varying thermal conditions.

Charles’s Law Problems with Constant Pressure

Charles’s Law problems with constant pressure involve calculating volume changes with temperature variations using the formula V1/T1 = V2/T2. In a sample problem‚ a gas occupies 5 liters at 20°C (293.15 K). At 80°C (353.15 K)‚ the volume increases proportionally. Using V2 = V1 × (T2/T1)‚ the new volume is approximately 6.02 liters‚ demonstrating the direct relationship between temperature and volume. Another example with decreasing temperature shows a gas occupying 10 liters at 100°C (373.15 K) reduces to about 8.66 liters at 50°C (323.15 K). Ensuring temperatures are in Kelvin and avoiding incorrect formula rearrangement are crucial for accurate solutions. These problems highlight how volume changes predictably with temperature under constant pressure‚ reinforcing the law’s principles effectively;

Step-by-Step Solutions for Charles’s Law Problems

Solving Charles’s Law problems involves a systematic approach to apply the formula V1/T1 = V2/T2. First‚ identify the known values and the unknown variable. Convert temperatures to Kelvin by adding 273.15 to Celsius values. Plug the values into the formula and solve algebraically for the missing volume or temperature. For example‚ if a gas occupies 4.5 liters at 30°C (303.15 K)‚ what is its volume at 60°C (333.15 K)? Using V2 = V1 × (T2/T1)‚ V2 = 4.5 L × (333.15/303.15) ≈ 4.95 L. Always ensure units are consistent and check calculations for accuracy. These step-by-step solutions help clarify the direct relationship between volume and temperature‚ making problem-solving more straightforward and effective for understanding Charles’s Law.
