SCI10 Q4 - GRADE 10

1. Good afternoon! SCI10 Q4 MODULE 1.2

2. Jacques charles (1746-1823) French inventor, scientist, mathematician, and balloonist. Known for his CHARLES’ LAW

3. CHARLES’ LAW States that volume is directly proportional to the temperature at constant pressure

4. CHARLES’ LAW

5. CHARLES’ LAW computation

6. Sample problem no. 1 A syringe contains 56.11mL of gas at 311K. Determine the volume that the gas will occupy if the temperature is decreased to 400 K. V2 = 72.17mL

7. Sample problem no. 2 A gas has an initial volume of 3480mL and an initial temperature of -70°C. What must be the temperature of the gas in Kelvin if its volume is reduced to 2450mL? T2 = 143.02K

8. Sample problem no. 3 If 540mL of nitrogen at 0.00°C is heated to a temperature of 100.0°C, what will be the new volume of the gas? V2 = 737.9L

9. Charles’ law application

10. Key concepts Volume is directly proportional to the Temperature ↑ V ↑ T and vice versa Pressure and mole is constant. Gen. Formula:
