q( Joules) = mass grams * specific heat * change in temperature
90 kj = 90000 Joules
2 kg = 2000 grams
90000 Joules = (2000 g)( SP )(200 C - 80 C)
90000 = 240000(SP)
0.375 J/gC
( The actual specific heat of copper is 0.385 J/gC, so close enough for the problem type )
Minus 273 degrees Celsius is equivalent to 0 Kelvin, which is known as absolute zero. At this temperature, molecular movement nearly ceases and all heat energy is removed. It is the coldest possible temperature in the universe.
Zero degrees Celsius is about the same as 273 Kelvin. Zero degrees Kelvin is a temperature that has yet to be reached in the lab, or anywhere in the known universe because at zero Kelvin mass ceases to have volume. 0 Kelvin, although only theoretical, is the lowest temperature possible, therefore zero Kelvin is much, much colder.
The temperature of the liquid water remains at 0 degrees Celsius until it freezes and begins to solidify. During this phase change, it will still be at 0 degrees Celsius until all the liquid has turned to solid ice.
The time it takes for water to freeze at 80 degrees Celsius depends on various factors such as the volume of water, the container it is in, and the rate at which heat is being removed. Generally, water freezes faster at higher temperatures, so it could freeze within a few hours at 80 degrees Celsius.
The outback Queensland town of Cloncurry originally held the record for the highest known temperature in the shade, at 53.1 °C (127.5 °F) on 16 January 1889. The Cloncurry record was later removed from Australian records because it was measured using unsuitable equipment (that is, not in a Stevenson screen, which only became widespread in Australian usage after about 1910).
The temperature at which no more energy can be removed from a substance is known as absolute zero. This is the lowest possible temperature that can be reached, at which the particles of the substance have minimal thermal motion. It is defined as 0 Kelvin or -273.15 degrees Celsius.
6.276 kJ
-273.15 degrees Celsius (-459.67 degrees Fahrenheit) is the temperature at which no more energy can be removed from matter.It is called Absolute Zero and marks the 0 for the Kelvin and Rankine scale.

That sounds like a description of the temperature known as "absolute zero". This temperature is zero kelvin; it is also approximately -273 degrees Celsius.
Absolute zero is the temperature at which no energy can be removed from matter. At this temperature, particles have minimal motion and all thermal energy is lost. It is equivalent to -273.15 degrees Celsius or 0 Kelvin.
Minus 273 degrees Celsius is equivalent to 0 Kelvin, which is known as absolute zero. At this temperature, molecular movement nearly ceases and all heat energy is removed. It is the coldest possible temperature in the universe.
Steam can reach temperatures of up to 100 degrees Celsius (212 degrees Fahrenheit) at sea level. The temperature of steam is influenced by factors such as pressure, volume, and the amount of heat added or removed from the system.
The maximum cold temperature that things can reach is absolute zero, which is 0 Kelvin or -273.15 degrees Celsius. At this temperature, particles stop moving, and all thermal energy is removed from the system.
Zero degrees Celsius is about the same as 273 Kelvin. Zero degrees Kelvin is a temperature that has yet to be reached in the lab, or anywhere in the known universe because at zero Kelvin mass ceases to have volume. 0 Kelvin, although only theoretical, is the lowest temperature possible, therefore zero Kelvin is much, much colder.
