What else can I help you with?
Waxy material that melts gradually starting at 52 Celsius and finishes at 65 is it a pure substance mixture?
The waxy material described is a pure substance. It exhibits a melting point range, suggesting a specific compound with a defined melting temperature range, rather than a mixture of multiple substances with varying melting points.
At What temperature does fine silver melt?
Pure silver melts at1763.474 °F.This is equivalent to 961.93 °C.
How can you tell a pure substance from a mature by its boiling point?
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
Why is melting point of pure water 44 degree celsius?
The melting point of pure water is actually 0 degrees Celsius. At this temperature, water transitions from a solid (ice) to a liquid state. The value you mentioned (44 degrees Celsius) seems to be incorrect.
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
What temperature will liquid sodium evaporate?
pure sodium melts at 97 degree celsius and boils at 882 degree celsius but no idea of evaporating temperature.......
Why is it that the -40 degree Celsius equals the -40 degree Fahrenheit?
That is pure coincidence.
What is the amount of heat needed to increase the temperature of a certain mass of a substance by 1 degree Celsius?
The heat capacity of a substance is the amount of heat required to raise the temperature of a defined amount of pure substances by one degree (Celsius or Kelvin). The calorie was defined so that the heat capacity of water was equal to one.
What is the pH of pure water at 70 degree Celsius?
7
What degree does ice start to melt in Celsius?
Zero degree (if we talk about destilled or reasonably pure water), for sea ice it's typically more around -4 degrees.
Waxy material that melts gradually starting at 52 Celsius and finishes at 65 is it a pure substance mixture?
The waxy material described is a pure substance. It exhibits a melting point range, suggesting a specific compound with a defined melting temperature range, rather than a mixture of multiple substances with varying melting points.
What is freezing point of pure water?
0 degree Celsius or 32 degrees Fahrenheit.
At What temperature does fine silver melt?
Pure silver melts at1763.474 °F.This is equivalent to 961.93 °C.
Which is a larger change in temperaturea change of 1 Celsius degree or 1 Fahrenheit degree explain?
1 Celsius degree.A Celsius degree is 1/100 of the difference between the melting and boiling points of pure water whereas a degree Fahrenheit is 1/180 of the same range.
What is the most dense pure water at 1 degree Celsius pure water at 4 degrees or seawater?
Seawater, then pure @ 4 degrees C.
Is ice a substance or mixture?
Ice is water (H2O) in it's solid state. It is a substance because it is entirely composed of one molecule and is not "mixed" with anything.
Freezing point of pure substance 21 degrees what is the melting point?
The melting point of a substance is the same as its freezing point in a closed system. Therefore, if the freezing point of a pure substance is 21 degrees Celsius, its melting point would also be 21 degrees Celsius.
