What else can I help you with?
An ordinary glass is filled to the brim with 350 mL of water at 100 C If the temperature decreased to 20C how much water could be added to the glass?
Difference in volume = (initial volume) (coefficient of volume expansion of water) (difference in temperature) coefficient of volume expansion of water=0.0002ml/degree celsius (not sure about the value. Better get help from a teacher.)
Can ordinary water be boiled in 95 degree Celsius or 105 degree Celsius?
pure water (with no impurities added ) can only boil at 100 degrees Celsius , no other temperature . But if we add impurities to it than the temperature at which the water will boil can increase or decrease. Another point is that when we increase or decrease the atmospheric pressure, the temperature at which ordinary water boils (i.e.100 degrees Celsius) can also increase or decrease.
What is mean temperature?
The word "mean" means average. The mean temperature is the average temperature. To calculate it you add all the temperatures together and divide by the number of temperatures you added.
Compare the temperature of a cup of ice with and without salt added to it?
They would be relatively the same temperature, it's just the melting point which is changed.
What happened when impurity is added in phenol water system?
the critical solution temperature for phenol water system increases

Why is boric oxide added in ordinary glass?
Boric oxide is added to ordinary glass to increase its thermal resistance and chemical durability. It also helps to lower the melting temperature of the glass batch, making the manufacturing process more energy-efficient.
Why is boric oxide added to ordinary glass?
Boric oxide is added to ordinary glass to increase its resistance to heat and chemical corrosion. It also helps reduce the coefficient of thermal expansion, making the glass less likely to break from sudden temperature changes.
Why boron oxide is added while preparing ordinary glass?
Boron oxide is added to ordinary glass to increase its thermal and chemical resistance. This helps the glass to withstand temperature changes and exposure to harsh chemicals better, making it more durable and suitable for various applications.
Why boric oxide added to ordinary glass?
Boric oxide is added to ordinary glass to increase its thermal resistance and chemical durability. It helps reduce the coefficient of thermal expansion, which makes the glass less likely to shatter when exposed to rapid temperature changes. Boric oxide also improves the glass's resistance to chemicals and weathering.

What element was added to ordinary table salt?
This element is iodine, added as potassium iodide or potassium iodate.
Added to ordinary table salt to control thyroid trouble?
iodine, (I)
When you add sugar to the boiling hot water the temperature is increased decreased or stayed the same?
The temperature of the boiling water would be decreased for a short time due to the temperature of the sugar being at room temperature. If you have ever made a batch of jam you can see how it works. The initial 'jam' solution is brought to a rolling boil [a boil which cannot be stirred down], then the sugar is added and quickly stirred in. The 'jam' returns to it's non-boiling state for about 2-3 minutes before it returns to a rolling boil.
How is he melting curve of duplex DNA affected by adding a small amount of ethanol?
If a DNA strand is denatured, it is generally as a result of an increase in temperature. If monitored, the absorbance can be graphed as a function of temperature. The midpoint in the resulting curve is the melting point. The melting curve can be altered by decreasing the ionic concentration, causing an decrease in the melting temperature. This is due to the Poly-anion nature of the DNA helix. When the ionic strength is decreased, the stability of the DNA strand decreases. When a small amount of ethanol is added, the non-polar effect has the biggest impact. When EtOH is added, the non-polar nature of the solution is decreased, resulting in a decreased importance of the hydrophobic forces on the stability of the helix, resulting in a lower melting temperature.
Two numbers can be added or multiplied in any order?
In ordinary maths, yes.
What operation does decreased by indicate?
When a number is decreased by another number subtraction is the mathematical process used. When a number is increased by another number the user added numbers together.
