How much ice water will it take to cool the sample to 20 degrees celsius?
To calculate the amount of ice water needed to cool the sample to 20 degrees Celsius, you would need the initial temperature of the sample, the mass of the sample, and the specific heat capacities of water and ice. With this information, you could use the equation q = m * c * ΔT to determine the quantity of ice water needed to cool the sample.
What is the melting point of pure ice?
The boiling point of pure water is typically about 100 degrees Celsius. This value can vary based on factors such as pressure. Additionally, impurities in a sample of water can alter its boiling point.
Which term is defined as a measure of the average kinectic energy of the particles in a sample?
Temperature is defined as a measure of the average kinetic energy of the particles in a sample. Temperature determines the direction of heat transfer between two bodies and is typically measured in degrees Celsius or Fahrenheit.
What will be the new volume of a 1.75 L sample cooled from 25 degrees celsius to 0 degrees celsius at constant pressure?
The volume of the sample will decrease as it cools down due to thermal contraction. To calculate the new volume, you can use the formula for thermal expansion: V2 = V1 * (1 + β*(T2 - T1)), where V1 = 1.75 L, T1 = 25°C, T2 = 0°C, and β is the coefficient of volume expansion for the substance at constant pressure.
The specific heat of lead is 128 kg degrees Celsius How much heat is needed to raise the temperature of a kg sample of lead by 10 degrees Celsius?
The relevant equation behind this problem is Q=m*c* ΔT Where Q is the energy that must be added to or taken from the system, m is the mass of the object, c is the objects specific heat, and ΔT is the change in temperature in Celsius or Kelvin. Plugging in the given values we get that Q=.015kg * 128J/(kg*C) * 10C=19.2J. Therefore, you need 19.2 joules of heat in order to raise the temperature of a .015kg sample of lead by 10 degrees Celsius.
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.
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.
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.
Why does salt water melt faster than water?
Adding salt to water lowers the temperature at which water freezes from 0 degrees Celsius to several degrees colder than that (depending on how much salt is added). Practically what that means is that a sample of pure water at -1 degrees Celsius will be frozen solid, but a sample of salt water at the same temperature will remain liquid since its freezing point is lower that.
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.
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.
The vapor pressure of a sample of boiling water is 380 torr The temperature of the water is?
The temperature of the water is 100 degrees celsius.
