How much heat would be required to raise the temperature of 17.8 g Ag by 22C?
The answer is 4,18 joule.
Explain why water is not suitable as a liquid in the thermometer?
Because the water would freeze when the temperature drops below 0 degrees Celsius
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
Explain the change in rate of photosynthesis as the water temperature increased from 18 degrees to 31 degrees?
Rate of photosynthesis decreases because the tissues which helps in transport of water stop transporting due to increase in temperature and hence change in rate of photosynthesis decreases.
A thimbleful of water at 100c has a highrer temperature than a swimming pool full of water at 20c but the pool has more thermal energy than the timble explain?
To raise the temperature of water in a thimble of water from 0 to 100 requires a small amount of thermal energy. To do the same with a swimming pool would require putting a huge amount of thermal energy into the water comparatively speaking.
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.
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.
How water is a good regulator of body temperature?
Water has an amazingly high specific heat compared to most substances so for example: adding or removing 1 Joule of energy from 1000 cm3 of water will change its temperature much less than it would change 1000 cm3 of most other substances.
What is the amount of energy needed to raise the temperature of object 1kg- you degree k?
You would need to know the specific heat capacity of the object, but presuming we're talking about water and perfect efficiency, you'd need exactly 1 joule.
Explain what would happen if a gas would reach absolutes zero temperature?
Solidification
Explain why water is not suitable as a liquid in the thermometer?
Because the water would freeze when the temperature drops below 0 degrees Celsius
What temperature would water be if steel was put in it?
That really depends on the temperature of the water and the steel !
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
Explain the change in rate of photosynthesis as the water temperature increased from 18 degrees to 31 degrees?
Rate of photosynthesis decreases because the tissues which helps in transport of water stop transporting due to increase in temperature and hence change in rate of photosynthesis decreases.
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.
