28 Consider one-dimensional steady state heat
conducting along x-axis (0 <xL), through a
plane wall with the boundary surfaces
(x = 0 and x = L) maintained at temperature of
0°C and 100°C. Heat is generated uniformly
through out the wall. Choose the CORRECT
statement
(a) The direction of heat transfer will be from
the surface at 100°C to the surface of 0°C.
(b) The maximum temperature inside the wall
must be greater than 100°C
(c) The temperature distribution is linear within
the wall
(d) The temperature distribution is symmetric
about the mid-plane of the wall​

Explanation:

Temperature is a physical quantity expressing hot and cold. It is measured with a thermometer calibrated in one or more temperature scales. The most commonly used scales are the Celsius scale (formerly called centigrade) (denoted °C), Fahrenheit scale (denoted °F), and Kelvin scale (denoted K). The kelvin (the word is spelled with a lower-case k) is the unit of temperature in the International System of Units (SI). The Kelvin scale is widely used in science and technology.

Average daily variation in human body temperature

Theoretically, the coldest a system can be is when its temperature is absolute zero, at which point the thermal motion in matter would be zero. However, an actual physical system or object can never attain a temperature of absolute zero. Absolute zero is denoted as 0 K on the Kelvin scale, −273.15 °C on the Celsius scale, and −459.67 °F on the Fahrenheit scale.

For an ideal gas, temperature is proportional to the average kinetic energy of the random microscopic motions of the constituent microscopic particles. This is now the basis of the definition of the magnitude of the kelvin.

Temperature is important in all fields of natural science, including physics, chemistry, Earth science, medicine, and biology, as well as most aspects of daily life.[
