What 2 things can make the pressure of gas rise?
1) Increase in heat 2)Decrease in volume
How can you decrease pressure of a gas in its container without changing the volume of gas?
lots of ways 1. cool it down 2. give it more space 3. remove some gas
In what volume ratio do hydrogen gas and oxygen gas react to form water?
Approximately twice as much volume of hydrogen as of oxygen: Both gases are diatomic and nearly ideal at normal temperature and pressure, and the atomic ratio of hydrogen to oxygen in water is 2.
What is the Celsius temperature of 1 mole of a gas that has an average kinetic energy of 3866 joules?
To find the Celsius temperature of a gas with an average kinetic energy of 3866 joules, we can use the formula for the average kinetic energy of a gas, which is ( KE = \frac{3}{2} nRT ). For 1 mole of gas (n = 1), this simplifies to ( KE = \frac{3}{2} RT ). Rearranging for temperature (T) gives ( T = \frac{2 \times KE}{3R} ). Using the gas constant ( R \approx 8.314 , J/(mol \cdot K) ), we find ( T \approx \frac{2 \times 3866}{3 \times 8.314} \approx 310.5 , K ). Converting this to Celsius gives ( T_{C} \approx 310.5 - 273.15 \approx 37.4 , °C ).
What are the six characteristics of a chemical change?
1. evolution of a gas 2. change in colour of the substance 3. change in temperature of the substance 4. formation of precipitate
What gas mark is 130c degrees?
Gas mark 5. x
What is 120degrees in gas mark?
120 degrees Celsius is equivalent to a Gas Mark 1/2 or 1. This setting is generally used for very low-temperature cooking, such as slow cooking or warming food. It allows for gentle heat, ideal for dishes that require a longer cooking time without browning.
What is 160 degrees in gas mark for cooking?
The equivalent gas mark would be 4, although all ovens vary so check the documentation that came with your own to be certain.
What is 165 f in gas mark?
To convert 165°F to gas mark, it corresponds to approximately gas mark 3. Gas mark 3 typically ranges from 325°F to 350°F. Therefore, 165°F is actually lower than gas mark 3; it would be closer to gas mark 1 or 2.
What is equivalent to 300 Degrees Fahrenheit in gas mark?
300 degrees Fahrenheit is equivalent to gas mark 2.
What is is gas mark 4 on an electric oven?
The answer is 190oC as can be seen from the below table:Fahrenheit Celsius Gas Mark 250°F 120°C Gas Mark ½ 275°F 135°C Gas Mark 1 300°F 149°C Gas Mark 2 325°F 162°C Gas Mark 3 350°F 176°C Gas Mark 4 375°F 190°C Gas Mark 5 400°F 204°C Gas Mark 6 425°F 218°C Gas Mark 7 450°F 232°C Gas Mark 8 475°F 246°C Gas Mark 9 500°F 260°C Gas Mark 9
When the Kelvin temperature of an enclosed gas doubles the particles of the gas .?
Temperature is proportional to energy and energy of gas particles is related to their velocity via E= 1/2mv2. So if the temperature doubles then the velocity of the individual particles increases by (4dE/m)1/2 =v
What 2 things can make the pressure of gas rise?
1) Increase in heat 2)Decrease in volume
Gas mark 2 equals how many degrees Celsius?
Gas mark 2 is equal to approximately 150 degrees Celsius.
How can you decrease pressure of a gas in its container without changing the volume of gas?
lots of ways 1. cool it down 2. give it more space 3. remove some gas
Does 1 tbsp of chlorine in 2 gals of water make a 100ppm solution?
At normal temperature and pressure, chlorine is a gas and I would be greatly surprised if you could measure 1 tbsp of chlorine.At normal temperature and pressure, chlorine is a gas and I would be greatly surprised if you could measure 1 tbsp of chlorine.At normal temperature and pressure, chlorine is a gas and I would be greatly surprised if you could measure 1 tbsp of chlorine.At normal temperature and pressure, chlorine is a gas and I would be greatly surprised if you could measure 1 tbsp of chlorine.
What does the expression mean cream puffs on a lower shelf?
That sounds like a cooking instruction for a non-fan oven. Without a fan there are temperature zones in a [gas] oven with the lower shelves at a lower temperature than the higher shelves. In a gas cooker, the setting for gas mark is [usually] the centre shelf; the top shelf is about 1 to 11/2 gas marks higher (about 25-37oF, 14-21oC hotter), the bottom shelf is about 1 to 11/2 gas marks lower (about 25-37oF, 14-21oC cooler) - the differences will be in the cooker's manufacturer's instructions. By putting the cream puffs of a lower shelf, they are baked at a lower temperature than that at which the oven has been set, allowing the baking of something else on a higher shelf at a higher temperature at the same time.
