Question

What is the highest temperature which can be created on earth for a sufficiently long time?
A)${{1500}^{0}}C$
B)${{2000}^{0}}C$
C)${{2500}^{0}}C$
D)$3000K$

Answer 1

Hint : Temperature is the measure of the amount of heat energy present in a body. The Celsius temperature range was originally defined by setting zero as the temperature at which water froze. Later onward zero Celsius is defined as the temperature at which ice melts. In kelvin zero degrees Celsius is equal to 273.15 kelvin.

Complete step-by-step solution:
Earth’s internal temperature increases with depth however that rate of increase is not linear. At the base of mantle the temperature will be around ${{3500}^{0}}C$ and the temperature at base of the crust is around ${{1000}^{0}}C$. at the center of the earth the temperature will be around ${{5000}^{0}}C$ and the temperature gradient within the lithosphere is quite variable depending on the tectonic setting.
The temperature at the earth's crust ranges considerably and at its outer edge, where it meets the atmosphere, the temperature at the earth crust is same as that of air.
The Earth crust remains the only place in the solar system where temperatures are stable so that life can continue to thrive on it. Average temperature of the earth has been steadily rising ever since humans started burning fossil fuels.
The correct option is D.

Note: A degree on the Fahrenheit scale is $\dfrac{1}{180}$ of the interval between the freezing point and the boiling point. The k which we use to represent temperature in kelvin is a Boltzmann constant. Thermal conductivity is usually measured in watts per meter-kelvin. Temperature gradient is defined as the rate at which temperature changes the most rapidly around a particular location.
