What is the density if water is cooled fron 4 degrees celcius to 0 degrees celcius?
The density of water increases as it cools from 4 degrees Celsius to 0 degrees Celsius. At 4 degrees Celsius, the density of water is 999.972 kg/m³, and at 0 degrees Celsius the density is 999.8395 kg/m³.
Which two gasses do not condense when air is cooled to 200 degrees centigrade?
Oxygen and Nitrogen are the two gases that do not condense when air is cooled to 200 degrees Celsius. They remain as gases at this temperature.
As water is cooled what happens to the density?
As water is cooled, its density increases until it reaches its maximum density at 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand as it freezes, which is why ice is less dense than liquid water.
500cm3 of ideal gas at 40 degrees Celsius and 200kpa absolute is compressed to 250cm3 and cooled to 20 degrees Celsius.What is the final absolute pressure?
Assuming the amount of gas remains constant, we can use the ideal gas law to calculate the final absolute pressure. The initial pressure (P1) is 200 kPa and the final volume (V2) is 250 cm3. The initial temperature (T1) is 40 degrees Celsius or 313.15 Kelvin, and the final temperature (T2) is 20 degrees Celsius or 293.15 Kelvin. Using the equation (P1 * V1) / T1 = (P2 * V2) / T2, we can solve for the final absolute pressure (P2), which is approximately 400 kPa.
As water is cooled from 4 degrees Celsius to 0 degrees Celsius it's density is what?
As water cools from 4 degrees Celsius to 0 degrees Celsius, its density decreases. This decrease in density is due to the formation of hydrogen bonds between water molecules, causing them to arrange in a more organized structure that takes up more space, decreasing the overall density of the water.
What would happen to the pressure if you cooled down the container?
The pressure inside the container would decrease.
A container of oxygen at 22 degrees Celsius and 740mm Hg is cooled to -22 degrees Celsius What is the new pressure of the gas?
Using the ideal gas law formula (P1/T1 = P2/T2), we can solve for the new pressure. The initial pressure at 22 degrees Celsius is 740mm Hg and the initial temperature is 22 degrees Celsius. The new temperature is -22 degrees Celsius. Plugging these values into the formula, the new pressure is approximately 463 mm Hg.
When water at 4 degrees Celsius is cooled it does it contract?
Yes, water contracts when cooled from 4 degrees Celsius because it is in its densest state at that temperature. As it cools further, it expands until it reaches its freezing point, at which point it expands again and turns into ice.
What pressure would you expect in a rigid container of 0 centigrade gas if you cooled it by 273 centigrade?
If you cool the container to -273 degrees Celsius, which is absolute zero, the gas would theoretically have zero pressure since all molecular motion would cease. In practice, achieving absolute zero is impossible, but as you approach it, pressure would approach zero.
What will happen as the temperature is gradually cooled at 10 degrees celsius?
It will gradually drop to below 10 degrees.
What 5 things expand when cooled?
water True, but only in the range 4 degrees Celsius to zero Celsius.
Can a car engine exceed 500 degrees?
No. Car engines are cooled by water (under pressure), so they run at or aground 100 degrees Celsius. Of cause in the combustion chamber and at the exhaust temperatures are much higher.
What state change occurs when the gas is cooled to 100 degrees Celsius?
gas to a liquid
What is the density if water is cooled fron 4 degrees celcius to 0 degrees celcius?
The density of water increases as it cools from 4 degrees Celsius to 0 degrees Celsius. At 4 degrees Celsius, the density of water is 999.972 kg/m³, and at 0 degrees Celsius the density is 999.8395 kg/m³.
When a container of gas is cooled what happens to the gas inside?
Gas pressure decreases when cooling down a closed container.
Which two gasses do not condense when air is cooled to 200 degrees centigrade?
Oxygen and Nitrogen are the two gases that do not condense when air is cooled to 200 degrees Celsius. They remain as gases at this temperature.
Which element will condense when cooled at room temperature from 100 Celsius?
At room temperature (around 25 degrees Celsius), the element that will condense when cooled from 100 degrees Celsius is water. Water vapor at 100 degrees Celsius will condense into liquid water when cooled to room temperature due to the lower temperature causing the vapor to lose energy and convert back to its liquid state.
