Water reaches maximum density at 4 degrees Celsius
Pure water reaches its maximum density at a temperature of approximately 4 degrees Celsius. This is why water typically contracts as it cools below this temperature, but expands as it freezes into ice.
When it reach zero degree Celsius.
It is theoretical because cell density cannot be forced to reach maximum density.
The maximum temperature that wood flames can reach is around 1,100 degrees Celsius (2,012 degrees Fahrenheit).
Water is at a minimum temperature when it is frozen, which is 0 degrees Celsius or 32 degrees FahrenheitFrom my high school memory, I recalled that water has minimum volume when at 4 degrees Celcius. This is why it is able to penetrate rocks as it is cooling and then crack them apart once it freezes again.Then I found this site http://www.simetric.co.uk/si_water.htmwhich statesAt 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml,1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ftandWhen water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
The maximum temperature that the hottest burning wood can reach is around 1,100 degrees Celsius (2,012 degrees Fahrenheit).
The maximum temperature that boiling water can reach is 212 degrees Fahrenheit (100 degrees Celsius) at standard atmospheric pressure.
The reason a fingertip did not reach to 40 degrees Celsius when immersed in a 40 degree Celsius of water is because of the body heat of the fingertip.
Water boils at 100 degrees Celsius at standard atmospheric pressure.
It is absolutely impossible to exactly calculate the maximum temperature in SUN. But based on its surface area and the quantum of Hydrogen it can hold, it is estimated that at the core the temperature will be of the order of 1.4 million degree Celsius
The maximum temperature that ovens can reach is typically around 500 degrees Fahrenheit (260 degrees Celsius). Ovens can get as hot as 550 degrees Fahrenheit (288 degrees Celsius) for some models, but this can vary depending on the type of oven.
A microwave can reach temperatures of around 212 degrees Fahrenheit (100 degrees Celsius) when operating at its maximum power.
