Because temperature is a measure of the microscopic energy of atoms (or molecules), the temperature doubles if the microscopic energy doubles. That being said, going from 10°C today to 20°C tomorrow isn't doubling the temperature (even though 20 is twice ten).
No. It really makes no sense to compare two temperatures in Celsius - or Fahrenheit, for that matter - saying that one temperature is hotter than the other, by such-and-such a factor. This sort of thing only makes sense in an absolute scale, such as Kelvin, which has no negative temperatures.
Just hearing that one object is “twice as hot” as another with no context, though, is meaningless because there's more than one absolute temperature scale.
For example, a 40 degree object is twice as hot as a 20 degree object.
So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees. Half of 10 degrees would be a very chilly -131.5 degrees Celsius.

Temperature is a measure of the amount of heat stored in a substance. The molecules of a gas are much farther apart than molecules in a solid or liquid. A liquid at 20C is twice as hot as the liquid at 10C. The degrees on the Celsius scale are larger than degrees on the Fahrenheit scale.
20 degrees C is not twice as hot as 10 degrees C, however, because there is no such thing as “no temperature” when it comes to the Celsius scale. When converted to Fahrenheit, it's clear: 10C=50F and 20C=68F, which is clearly not twice as hot. I hope that makes sense.

A temperature of 25° C is 298° K absolute, and 50° C is 323 K, so the latter is clearly not anywhere near twice the former.
The value is 1.417 x 10^32 Kelvins (Subtract 273.15 to get the Celsius temperature - ha ha!). It is supposed that, at this temperature, the energy of atoms is greater than the energy of the forces that hold it together. So matter, as we understand it, cannot exist. Infinite temperature is, as the kids say, not a thing.
The key physiological mechanisms underlying this effect aren't certain yet. However, we believe that warming of the skin increases electrical signals in sensory neurons. These neurons relay signals to the spinal cord, and neurons in the spinal cord then pass along the signals to the brain.
Some cold receptors respond when we touch something really hot (over 113 degrees Farenheit or 45 degrees Celsius), which is why sometimes the hot water in your showers can feels icy cold for a split-second. This phenomenon is called paradoxical cold, but scientists aren't sure why this happens.
When the atmospheric moisture content (i.e. relative humidity) is high, the rate of evaporation from the body decreases. In other words, the human body feels warmer in humid conditions.
Heat rises – Blame physics: hot air rises while cold air sinks. That means your upstairs typically gets hotter than your lower levels, even if your air conditioner's working in overdrive. Your roof's hot, too – Unless you have shady tree cover, your roof absorbs a ton of heat from the sun.
Thus, you could never say 80 degrees Fahrenheit is twice as hot as 40 degrees Fahrenheit. Because of the absence of zero, even though you have equal intervals, you cannot compute ratios on these variables.
The temperature may be an objective number, but how we experience it is not. Culture influences the biology and psychology of thermal comfort, shaping what our bodies are used to dealing with and how our homes and businesses are set up to adapt.
Celsius and Fahrenheit are two temperature scales. The Fahrenheit and Celsius scales have one point at which they intersect. They are equal at -40 °C and -40 °F.
Water temperatures are slow to heat up, and just as slow to cool down. Water is very "stubborn" to change temperature. It takes 4 times the energy to heat up water than to heat air. Water also "feels" colder because water is a more efficent medium than air to cool our body down.
A temperature of 40 degrees is twice that of 20 degrees no matter which scale it is measured on.
ANSWER: Short answer: A temperature of 273 Celsius (Centigrade) is twice as hot as zero degrees Celsius.
10 degrees on any scale will always be colder than 20 degrees. Unless one is talking about negative numbers, where it would be the other way around, this will always be true. So, in answer to your question, 10 degrees Celsius is colder than 20 degrees Celsius.
Water is converted to solid state (ice) at 0 C, which is the freezing point of water.
At 20°C, water would be in its liquid state. It is the normal boiling point of water. At 20C pure water can be a gas, a nonequilibrium mix of gas and liquid, a gas-water equilibrium, if no head space and applied pressure above the vapor pressure only a liquid, finally at very high pressure two forms of “ice".
Molecules in the liquid phase can lose a bit of energy and solidify whilst solid water (ice) can gain some energy and melt.So both the liquid and solid state exist at 0-degree Celsius.
