It contains salt and other impurities.

Sea water has a lower freezing point and higher boiling point than pure water due to the presence of dissolved salts. The salt lowers the freezing point by interfering with the formation of ice crystals, while the boiling point is raised because the presence of salts increases the boiling point of the solution.

How many watts to heat 1 liter of water?
It takes about 4.18 Joules of energy to heat 1 gram of water by 1 degree Celsius. Therefore, to heat 1 liter (1000 grams) of water by 1 degree Celsius, it would require about 4180 Joules. Converting this to watts depends on the time taken to heat the water.
What precautions must be taken by patients with boils?
Patients need to be warned against picking at or squeezing boils because of the danger of spreading the infection into other parts of the skin or bloodstream.
What is the coefficient expansion of transformer oil?
The coefficient of expansion for transformer oil is typically around 0.0007 per degree Celsius. This means that for every 1 degree Celsius increase in temperature, the volume of the transformer oil expands by approximately 0.07%. This expansion needs to be taken into account when designing and operating transformer systems to prevent any issues due to thermal expansion.
Can a human survive on Antarctica where the temp is below 50 degree Celsius?
No, humans cannot survive in temperatures below -50 degrees Celsius without adequate protection and shelter. The extreme cold in Antarctica would lead to hypothermia and death if precautions are not taken.
Why does ice at 0 degree celsius cools better than water at 0 degree celsius?
Ice at 0 degree Celsius is able to absorb more heat energy from its surrounding environment to melt and increase its temperature, compared to water at 0 degree Celsius which needs to first convert into ice before it can absorb additional heat energy. This latent heat of fusion process makes ice more effective at cooling than water at the same temperature.
What is the SI base unit for temperature called?
The SI base unit for temperature is called the Kelvin (K).

If a substance freezes aat -58 c then what would it melt at?
If a substance freezes at -58°C, it would typically melt at the same temperature, as the freezing and melting points are usually the same for a substance.
What precautions must be taken by patients with boils?
Patients need to be warned against picking at or squeezing boils because of the danger of spreading the infection into other parts of the skin or bloodstream.

How do you know when an endothermic reaction has taken place?
When something melts, boils, evaporates or sets fire.
When water at 4 deg Celsius taken in a glass is cooled to 1 deg Celsius what will be level of water?
increases

Can chloroform be heated to ninety degrees celsius in an open container?
Yes, chloroform can be heated to 90 degrees Celsius in an open container as long as proper caution is taken due to its flammability and toxicity. It is important to handle chloroform carefully and in a well-ventilated area to avoid any risks.
Is water boils at 100 degrees celsius?
Water does boil at 100 celsius. However evaporation occurs at any temperature. so for boiling to occur a specific temperature is required which it is called the boiling point of that substance whereas evaporation occurs at any temperature Water only boils at the temperature of 100 degrees Celsius at standard atmospheric pressure. So up a mountain, where the air pressure is reduced, water boils at a lower temperature. Water boils at sea level at 100 degrees Celsius
What is the temperature taken as lower fixed point in Celsius scale?
The two main fixed points in the Celsius scale are: Zero degrees the freezing point of water and 100 degrees its boiling point. Any temperature below freezing are minus values, the lowest being -273 degrees absolute zero the point where everything stops.
What is the highest temperature in degrees celsius to be recorded in the UK and where and when was this taken from?
134
