What water does at 100 and degc?
It boils
The volume of a gas is 605 liters at 27.0 and degC. The new temperature is -3.0 and degC. What is the new volume (Remember to convert temperatures to the Kelvin scale.)?
The new volume is 544,5 l.
What would happen to the solubility of potassium chloride in water as the water temperature increased from 25 and degC to 100 and degC?
The solubility increase from 38,7 g KCl/100g water to 40,7 g KCl/100 g water.
Does uranium boil or melt?
Melting point 1132 degC, boiling point 4131 degC
How many joules of heat are necessary to raise the temperature of 25 g of water from 10 degrees Celsius to 60 degrees Celsius?
For an approximate calculation: specific heat capacity for water = 4.18 J/(g*degC) (how much energy is required per gram per change in degrees C) mass = 25g Change in temperature = 60-10 = 50 degC energy required = mass * change in temperature * specific heat capacity = 25g * 50 degC * 4.18 J/(g*degC)
If the temperature changes by 100 K by how much does it change in and degC?
A change of 100 degrees K is equal to a change of 100 degrees Celsius.
What is the average temperature of a nuclear reactor?
A PWR has an inlet water temperature of 275 degC and outlet 325 degC
What is the freezing point of an aqueous 2.65 m calcium chloride solution?
dT = (i)(Kf)(m) is the equation that can be used to model the freezing point depression. dT represents the change change in temperature. i represents the amount of ions formed from the dissolution of the solute. Kf represents the constant of the freezing point depression of water. m is the molality of the solute in solution. dT = (3)(1.86 degC/m)(2.65m) dT = 14.8 degC 0-14.8 degC = -14.8 degC So the freezing point is -14.8 degrees C. The reason why this value was subtracted from zero is because the presence of a solute lowers the freezing point.
What water does at 100 and degc?
It boils
What would happen to a sample of water at 30 and degC if it is heated until the temperature reaches 120 and degC?
Water is transformed in vapors.
The specific heat of a certain type of cooking oil is 1.75 cal(g and middot and degC). How much heat energy is needed to raise the temperature of 2.40 kg of this oil from 23 and degC to 191 and degC?
The energy is 103,6 kcal.
At 30 and degC what state is bromine in?
Liquid
When A balloon has a volume of 10500 liters and the temperature is 15 and degC. If the temperature were -25 and degC what would the volume of the balloon be?
It would be approx 9042 litres.
A solid substance with a mass of 200 grams is at its melting point temperature in a calorimeter While the substance changes from a solid to a liquid at the same temperature the 400-gram mass of water?
(4.184 J/g*degC)(400g)(40.0*degC-80.0*degC)+(200g)
The volume of a gas is 605 liters at 27.0 and degC. The new temperature is -3.0 and degC. What is the new volume (Remember to convert temperatures to the Kelvin scale.)?
The new volume is 544,5 l.
If I dissolve 50 grams of salt in 1000 mL of water and the temperature decreases from 30.5 and degC to 35.6 and degC what is the heat change enthalpy of reaction Was this an exothermic or endothermic?
How can the temperature DECREASE from 30.5ºC to 35.6ºC? That's an INCREASE in temperature. So, assuming you meant the temperature INCREASED to 35.6ºC, then it is an endothermic reaction.q = mC∆T = (1000 g)(4.184 J/g/deg)(5.1 deg) = 20,920 J = 20.9 kJ. This is the heat change for this reaction.
What are the properties of sulferdioxide?
Sulphur dioxide is a colourless liquid or pungent gas, which is the product of the combustion of sulphur on air. Its melting point is -72.7 degC, its boiling point is -10 degC and its relative density is 1.43.
