What is the enthalpy change for converting 1 mol of ice at -50 degrees celsius to water at 70 degrees celsius?
The enthalpy change for converting 1 mol of ice at -50 degrees Celsius to water at 70 degrees Celsius is the sum of the enthalpy changes for the following processes: heating ice from -50 degrees Celsius to 0 degrees Celsius (heat of fusion), melting ice at 0 degrees Celsius, and heating water from 0 degrees Celsius to 70 degrees Celsius (specific heat of water).
What is the STP for Oxygen?
Standard temperature and pressure (STP) for oxygen is defined as a temperature of 0 degrees Celsius (273.15 Kelvin) and a pressure of 1 atmosphere (101.325 kilopascals). At STP, one mole of oxygen gas occupies a volume of 22.4 liters.
What phase is water in at 1 ATM pressure and 150 and degC?
Water is in the liquid phase at 1 ATM pressure and 150 degrees Celsius. At this temperature and pressure, water exists as a liquid.
The temp of boiling water in Celsius?
The temperature of boiling water in Celsius is 100 degrees.
At 1250 mm Hg and 75 degrees Celsius the volume of a sample of ammonia gas is 6.28 L What volume would the ammonia occupy at STP?
Using the combined gas law, we can relate the initial and final conditions of the gas: P1V1/T1 = P2V2/T2. At STP (Standard Temperature and Pressure), the conditions are 1 atm and 0 degrees Celsius. Convert 1250 mm Hg to atm and 75 degrees Celsius to Kelvin. With this information, you can then calculate the final volume of the ammonia gas at STP.
What is the density of o2 at 1 ATM and 20 degrees celsius?
The density of O2 at 1 atm and 20 degrees Celsius is approximately 1.429 g/L.
What is the freezing point of water at 1 ATM?
The freezing point of water at 1 ATM (standard atmospheric pressure) is 0 degrees Celsius or 32 degrees Fahrenheit. At this temperature, water changes from a liquid to a solid state.
How hot does it have to be for ice to turn into water?
32 degrees Fahrenheit, or 0 degrees Celsius, is the melting point of water at 1 atm.
What state is a substance in at 1 ATM and -50 degrees Celsius?
The state of a substance at 1 ATM and -50 degrees Celsius would depend on the substance. For most substances, at -50 degrees Celsius and 1 ATM pressure, they would typically be in a solid state.
What is the term used for 0 degrees C and a ATM?
A temperature of 0 degrees Celsius and a pressure of 1 atmosphere is considered standard temperature and pressure or STP.
What temperature Celsius does water freezes?
Pure water freezes at 0 degrees Celsius when at sea level (1 atm, or 760 torr). It boils at 100 degrees Celsius under the same conditions.The freezing temperature of water is 0 degrees Celcius.
What does STP occur at?
1 atm=760 mm Hg= 760 torr =101.325 kPa and 0 degrees Celsius
What is the volume 1 g or water at 4 degrees celsius and a pressure at 1 ATM?
The volume of 1 g of water at 4 degrees Celsius and 1 ATM pressure is approximately 1.002 mL.
What is the most useful thing to know about gases in STP?
Any gas at STP is 0 degrees Celsius and 1 ATM when at 22.414L.
What is atmospheric pressure at sea level and at 0 degrees Celsius called?
1 ATM of pressure and 0 c is known as 'Standard temperature and pressure' (STP)
What degrees celsius does water boil at?
Water boils at 100 degrees Celsius at standard atmospheric pressure (1 atm).
22.41 L is the volume of 1 mol of gas at?
STP (standard temperature and pressure), which is 0 degrees Celsius and 1 atm pressure.
