| Temperature Meter: This meter measures the temperature of the gas inside the ideal gas container. You must attach the temperature meter to a red hotspot on the container (see Container (Ideal Gas)). Only the probe connects to the hotspot on the container. The meter itself appears to the left. You can move the meter, but you cannot delete it. To delete the meter, you must delete the probe. In the temperature meter's Properties Box, you can set it to measure temperature in either Kelvin (default) or Celsius. You must place a temperature meter to plot temperature using the graph tool.
