Solve this problem using Charles's Law: A sample of carbon dioxide in a pump has a volume of 21.5 mL, and it is at 50.0 °C. Find the new volume of carbon dioxide in the pump if the temperature is raised to 75°C

23.16 mL

Solve this problem using Boyle's Law: An 18.10mL sample of gas is at 3.500 atm. What will be the volume if the pressure becomes 2.500 atm, with a fixed amount of gas and temperature?

25.34 mL

What is the formula for Boyle's Law?

P1V1 = P2V2

What is the formula for Charles's Law?

V1 / T1 = V2 / T2

Solve this problem using GL's gas law: Determine the pressure change when a constant volume of gas at 2.00 atm is heated from 30.0 °C to 40.0 °C.

2.06 atm

What is the formula density?

D = M/V

What is the formula for GL's gas law?

P1 / T1 = P2 / T2

What is the formula for combined gas law?

P1V1 / T1 = P2V2 / T2

Endothermic

Movement of a liquid or gas where the warm part rises and the cold part sinks is called, El movimiento de un líquido o gas donde la parte caliente sube y la parte fría baja se llama

convection

The amount of heat needed to raise the temperature of a substance by 1 degree celsius is called the

Specific heat capacity

Solve this problem using Q = MCΔT: 5.0 g of copper was heated from 20°C to 80°C. How much energy was used to heat Cu? (Specific heat capacity of Cu is 0.092 cal/g °C)

27.6 J

Solve this problem using Q = MCΔT: How much heat is released when 30 g of water at 96°C cools to 25°C? The specific heat of water is 1 cal/g°C.

2130 J

What does this symbol mean: Δ

Change

Measuring the amount of heat released or absorbed during a reaction is called, La medición de la cantidad de calor liberado o absorbido durante una reacción se llama
