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 )

What is about minus 273 degrees celsius?

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.


How cold is zero degrees kelvin?

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.


When heat is removed from liquid water at 0 degrees C what happens to its temperature?

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.


How long does it take for water to freeze at 80 degrees c?

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.


What is the hottest temperature ever recorded in Cloncurry Queensland in January 1889?

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?

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.

What is the temperature called when no Energy can be removed from matter?

That sounds like a description of the temperature known as "absolute zero". This temperature is zero kelvin; it is also approximately -273 degrees Celsius.


What is the temperature called at which no energy can be removed from matter?

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.

How hot can steam get and what factors influence its temperature?

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.


What is the maximum cold things can be?

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.
