What else can I help you with?
The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
The temperature must decrease by 275 degrees Celsius to reach the freezing point of helium at -272 degrees Celsius.
How many moles are contained in 4.67 L sample of gas 33 degrees Celsius and 199 kpa?
how many moles are contained in 4.67 L sample of gas at 33 degrees celcius and 199 kpa
When the temperature of a sample of water is -5 celiculs the is a?
When the temperature of a sample of water is -5 degrees Celsius, the water is in a solid state, as it is below the freezing point of water at 0 degrees Celsius. At this temperature, water molecules have slowed down and formed a crystalline structure, resulting in the solid state known as ice.
) The temperature of a sample of water changes from 10 and degC to 20 and degC when the water absorbs 100 calories of heat. What is the mass of the sample?
one calorie of heat is able to raise one gram of water one degree Celsius so 400 calories could raise 1g of water 400 degrees, so it would raise the 80g by(400/80) 5 degrees Celsius plus the initial temp of 10 degrees, the 80g of water would have a final temp of 15 degrees Celsius
How many moles of nitrogen are contained in a 35.0g sample?
To find the number of moles of nitrogen in a 35.0g sample, you need to divide the mass of the sample by the molar mass of nitrogen. The molar mass of nitrogen is approximately 14.01 g/mol. Therefore, 35.0g / 14.01 g/mol = approximately 2.5 moles of nitrogen.
When a sample of water is heated past 100 degrees Celsius its past its?
When a sample of water is heated past 100 degrees Celsius, it is past its boiling point. At this temperature, water changes from a liquid to a gas.
If a sample is heated and rises in temperature by 12 degree celsius what is this temperature difference in kelvin?
The temperature difference in Kelvin is the same as in Celsius. So, if the sample rises by 12 degrees Celsius, it also rises by 12 Kelvin.
How much energy will the same glass sample gain when it is heated from 41.0 Celsius to 71.0 Celsius?
24 Joules
When the temperature of a sample of water is negative 5 degrees Celsius the water is?
When the temperature of a sample of water is -5 degrees Celsius, the water is frozen and in a solid state.
Can a sample of water maintain the same volume after being warmed by several degrees Celsius?
No, a sample of water will expand and increase in volume when warmed by several degrees Celsius due to thermal expansion.
A sample of nitrogen gas is collected over water at 20 degrees Celsius. The vapor pressure of water at 20 degrees Celsius is 18 mmHg. What is the partial pressure of the nitrogen if the total pressure?
The total pressure is the sum of the partial pressure of nitrogen and the vapor pressure of water. Therefore, the partial pressure of nitrogen is the total pressure minus the vapor pressure of water. Given that the total pressure is not provided in the question, we need more information to calculate the partial pressure of nitrogen.
Suppose I give you 2 kg of a substance at 90 degrees celsius with a specific heat of 0.75 calg degrees celsius how much ice water will it take to cool the sample to 20 degrees celsius?
The answer is 20 times 75.
The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
The temperature must decrease by 275 degrees Celsius to reach the freezing point of helium at -272 degrees Celsius.
How fast do you heat the sample when determining a melting point?
The apparatus used for determining the melting point will heat the sample at an appropriate rate. All you need to do is watch and note the point at which the sample melts, as should be demonstrated to you by your lab supervisor.
How warm should pee be for a urine sample to be considered valid?
The temperature of a urine sample should be around 98.6 degrees Fahrenheit (37 degrees Celsius) to be considered valid.
Which sample of water contains the most heat energy 10 g at 10 degreescelsius or 20 g at 10 degrees celsius?
The sample of water that contains the most heat energy is the 20 g sample at 10 degrees Celsius because it has double the mass of the 10 g sample. Heat energy is directly proportional to mass, so the sample with more mass will contain more heat energy.
What would happen to a sample of water at 30 degrees c if it is heated until the temperature reaches 120 degrees c?
The water would first heat up and reach its boiling point at 100 degrees Celsius. Once it reaches 100 degrees Celsius, it would start boiling and convert into steam at a constant temperature of 100 degrees Celsius until all the water has evaporated.
