    Measure Temperature
AI Thread Summary
Scientists measure extreme temperatures using various methods tailored to specific environments. For the Sun, techniques such as spectroscopy are employed to analyze light emissions. The Earth's upper atmosphere can be measured using satellite instruments that detect temperature variations. Insects are typically measured with thermocouples or infrared sensors, while the Moon's temperature is assessed through remote sensing data. The ocean floor's temperature can be inferred from geological studies, and liquid helium is measured using specialized cryogenic thermometers. Understanding these methods is crucial for accurate temperature assessment across diverse environments.

This is actually a question extracted from the physics book by Halliday.
How would you suggest measuring the temperature of (a) the Sun, (b) the Earth's upper atmosphere, (c) an insect, (d) the Moon, (e) the ocean floor and (f) liquid Helium?
Thanks first.:smile:

There's a section her devoted to homework problems. You'll also have to tell us how far you got and where you got stuck. We'll help you, but won't do it for you.

To get you thinking in a non-obvious direction, the answer to e) is 4C. Think about how I knew that without measuring anything and it will guide you to the solution.
 
I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
