If five liters of air at -50 degrees Celsius is warmed to 200 degrees Celsius what is the new volume if the pressure remains constant?
This is a nice question to work with. For a gas, the product (P x V) is proportional to 'T'. ('Pressure', 'Volume', 'Temperature') But we have to be careful, because the temperature has to be referenced to absolute-zero. For Celsius, that's -273.15. -50 C = 223.15 K 200 C = 473.15 K The change in absolute 'T' was (473.15 / 223.15) = 2.12 times as great (rounded) So the product (P x V) must also become 2.12 times as great. If 'P' remains constant, then 'V' must become 2.12 times as great = (5 x 2.12) = 10.602 liters. According to the gas law pV=nRT, given as isobaric situation Volume is directly proportional to temperature. v1/t1= v2/t2 => v2=v1*t2/t1 v2= 5*(200+273)/(-50+273) v2=5*473/223 v2= 8.663 L

What is the temperature in Celsius for water in the phase change of melting?
The temperature of water during the phase change of melting remains constant at 0 degrees Celsius until all the ice has melted. This is because the energy is utilized in breaking intermolecular bonds rather than increasing the temperature.
What is the state of Copper at 20 degrees celsius?
At 20 degrees Celsius, copper is in its solid state. Copper has a melting point of 1,085 degrees Celsius, so at 20 degrees Celsius, it remains a solid metal.
Is nitrogen a gas at 20 degrees?
Yes, at 20 degrees Celsius, nitrogen is a gas. Nitrogen has a boiling point of -196 degrees Celsius, so it remains in a gaseous state at 20 degrees Celsius.
Is a temperature in degrees Fahrenheit proportional to its equivalent temperature in degrees celsius?
Proportional, in mathematical terms, means that the ratio remains constant no matter what. But Celsius and Fahrenheit's ratio does not remain constant: 1 degree Celsius is equal to 33.8 degrees Fahrenheit, and 2 degrees C equals 35.6 degrees F. If you divide 35.6 by 2, it should equal 33.8, but since it does not, then therefore Celsius is not proportional to Fahrenheit.To convert F to C:F = C x 9/5 +32It is the plus 32 that makes the temperatures not proportional.C = (F - 32) x 5/9
How cold is absolute zero in Celsius?
Absolute zero is -273.15 degrees Celsius and -459.7 degrees Fahrenheit. Kelvin = degrees Celsius + 273.15
What is the state of nitrogen at 100 degrees celcius?
Nitrogen remains in a gaseous state at 100 degrees Celsius, as its boiling point is -196 degrees Celsius at standard atmospheric pressure.
A tire has a pressure of 325 kPa at ten degrees Celsius. If the temperature rises fifty degrees Celsius and the volume remains constant what is the new pressure?
Use the ideal gas law: P1/T1 = P2/T2. Rearrange the equation to solve for P2: P2 = (P1/T1) * T2. Plug in the values: P2 = (325 kPa / 283 K) * 60 degrees Celsius. Convert the temperature to Kelvin: 60 degrees Celsius + 273 = 333 K. Calculate the new pressure: P2 ≈ 361 kPa.
Is lead a solid or liquid at 100 degrees?
The melting temperature of a substance is dependent upon the pressure and specific volume. The melting temperature of liquid at standard pressure of 1atm (~100kPa) is 0 degrees Celsius.
A sample of Xenon gas at 20degree Celsius and 0.570 ATM is cooled to a pressure of 0.100 ATM If the volume remains constant What is the final Celsius temperature?
Using the ideal gas law, we can calculate the final temperature of the Xenon gas. Since the volume remains constant, we can use the combined gas law (P₁/T₁ = P₂/T₂) to solve for the final temperature. Rearranging the equation gives T₂ = (P₂ / P₁) * T₁. Plugging in the values, we get T₂ = (0.100 / 0.570) * 20 degrees Celsius = 3.51 degrees Celsius.
What is the state of matter for xenon at 1000 Celsius?
At 1000 degrees Celsius, xenon is in the gaseous state. Xenon is typically a gas at room temperature and pressure, and it remains gaseous even at higher temperatures like 1000 degrees Celsius.
What happens at 100 percent celsius?
At 100 degrees Celsius, water reaches its boiling point and starts to change from a liquid to a gas. This temperature remains constant until all of the liquid water has been converted into steam.
What portion of the atmosphere where temperature remains fairly constant?
It is the stratosphere atmospheric zone where the temperature stays fairly constant, at -60 degrees Celsius. The stratosphere layer contains the ozone layer.
What is water at 20 degree Celsius?
It just remains as water. The freezing point of water is 0 degrees Celsius, while the freezing point is 100 degrees Celsius. Therefore at 20 degrees Celsius, there is no change in state and it just remains as water.
What state would water be at 75 degrees celsius?
At 75 degrees Celsius, water is in a liquid state. It remains a liquid because this temperature is below its boiling point of 100 degrees Celsius at standard atmospheric pressure. Therefore, water at this temperature would be warm but not gaseous or solid.
How cold is ice?
Ice typically forms at 0 degrees Celsius (32 degrees Fahrenheit). Its temperature can vary depending on the environment, but it remains solid until it reaches its melting point.
What is State of copper at 800 degrees Celsius?
At 800 degrees Celsius, copper is in solid state. Copper has a melting point of 1085 degrees Celsius, so at 800 degrees Celsius, it remains in its solid form.
What is the temperature in Celsius for water in the phase change of melting?
The temperature of water during the phase change of melting remains constant at 0 degrees Celsius until all the ice has melted. This is because the energy is utilized in breaking intermolecular bonds rather than increasing the temperature.
