How much heat would be required to raise the temperature of 17.8 g Ag by 22C?
The answer is 4,18 joule.
When he vapor pressure of water is 70kpa the temperature of the water is?
At a vapor pressure of 70 kPa, the temperature of water would be approximately 63.5 degrees Celsius. This temperature corresponds to the boiling point of water at that specific pressure.
Why there is more heat in an iceburg than a pot of boiling water?
"Heat" doesn't refer to the temperature, but to the amount of thermal energy - for two substances of the same type, that would basically be the temperature multiplied by the mass. (For a more detailed analysis, you would also have to consider latent heat for phase changes, and an object's specific heat.) First, heat and temperature are not the same thing, a common misconception. All matter has what is called a "Specific Heat" (c) which is the amount of energy needed to raise its temperature by one degree Kelvin. Water for instance has a specific heat of 4181 J/(kg*K). (joule per kilogram per degree kelvin)
What would be the temperature of water at room temperature after 4 ice cubes are added in and melted after 2 hours?
Room temperature
You see a solid that looks like an ice cube but it does not melt at room temperature can the solid be frozen water explain?
yes it can be frozen water, because it hasn't melted yet, so it is still an ice cube.
How would you explain the temperature rise in the water?
The temperature rise because of the gangnam dance
How much heat would be required to raise the temperature of 17.8 g Ag by 22C?
The answer is 4,18 joule.
How can things have the same temperatures but different heats?
Two things can have the same temperature but different heats if they have different specific heats. For example, water has a specific heat of 1 joule per gram per degree. Iron has a specific heat of 0.45 joules per gram per degree. So, if you had 1 gram of water and 1 gram of iron, both at 25º, and you added 1 joule of energy, the temperature of water would go up 1 degree to 26º, but the temperature of iron would go up 2.2 degrees to 27.2º.
How do you convert centigrade to joule?
Centigrade (Celsius) is a unit of temperature, while joule is a unit of energy. There is no direct conversion between the two. To convert temperature to energy, you would need to consider other factors such as heat capacity and specific heat of the material.
Is there a link between the mass of water being heated and the temperature rise?
There is a link between the mass of water heated and how much that water rises in temperature. It's called the "heat capacity" of water. It takes 1 joule of energy to raise the temperature of 1 gram of water by 1 degree celcius (or kelvin). So knowing this you can work out how much hotter a specific amount of water would become if you applied a known amount of energy to it.
Explain what would happen if a gas would reach absolutes zero temperature?
Solidification
What temperature would water be if steel was put in it?
That really depends on the temperature of the water and the steel !
Which water freezes first boiling water cold water or room temperature.?
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
Do ice cubes melt faster in or outside water?
The temperature of the water and the temperature of the air would have to be factors in the answer. EDIT: Assuming the air and water are the same temperature, it would melt much faster in water. The thermal conduction is much higher.
What is the average temperature of water in the fridge?
It would depend on the temperature that the refridgerator was set at.
Which would melt more ice- a pot of hot water or a tub of warm water explain answer?
A pot of hot water would melt more ice because it has a higher temperature than a tub of warm water. The greater temperature difference between the hot water and the ice leads to faster heat transfer, causing the ice to melt more quickly.
What would happen if ice water was left out for hours?
well, the ice in it would melt, and the water would get warmer if it was in a hot climate,(a temperature warmer than the ice water) and if it was in a cold climate, (a temperature colder than the ice water) it would freeze or get colder.
