Two thermometers one graduated in Fahrenheit and the other in celsius are placed in a bath and the bath is gradually heated. At what temperature will both thermometer read the same???

Answer:
Explanation:
Like most of the quantities we will talk about in this section, temperature - or to be precise thermodynamic temperature - is one of the base quantities defined by the International System of Units. The internationally agreed base unit for temperature is the kelvin, named after the Irish mathematical physicist and engineer William Thomson (1824-1907). Thompson earned the title 1st Baron Kelvin in 1892, partly in recognition of his achievements in the field of thermodynamics, and partly due to his opposition to Irish home rule.
The SI unit for heat energy (or work or just energy) is the joule, although we sometimes refer to a unit of heat used in the centimetre-gram-second (CGS) system of physical units called a calorie. One calorie represents the amount of heat energy required to increase the temperature of one gram (one cubic centimetre) of pure liquid water by one degree Celsius (1 °C), or that is lost by one gram of pure liquid water as its temperature decreases by one degree Celsius.
The concept of heat is generally associated with that of temperature, and rightly so. They are of course closely related, but they are not the same thing. We often talk about a "heat wave" when temperatures are higher than normal in the summer, but even in the depths of winter, when temperatures fall below the freezing point of water, our environment is far from being devoid of heat. If it were, none of us would be here to talk about it. So what is the difference between temperature and heat?
Explanation:
-40 degrees
To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations. So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees.
