Urine would be found in the ureter. The ureters are tubes that carry urine from the kidneys to the bladder.
The opposite of urine would be something like clean water or another substance that is not waste or bodily fluid.
Urine gets its normal yellow color from a pigment called urochrome, which is a product of the breakdown of hemoglobin from old red blood cells. The concentration of urochrome in urine can vary depending on hydration levels and diet.
Urine turns into gas when heated to around 93°C (200°F) due to the evaporation of the water content in the urine. The urine doesn't completely turn into gas but instead releases water vapor and other compounds.
A substance is a solid if it has a definite shape and volume, and maintains its shape under normal conditions of temperature and pressure. Solids are rigid and have tightly packed particles arranged in a regular pattern. They do not flow like liquids or gases.
In a normal urinalysis, you would expect to find clear urine, no traces of blood, normal levels of protein, glucose, ketones, and pH, and no presence of bacteria or white blood cells.
Normal urine is sterile when voided and therefore does not constitute a biohazard. Urine left in open containers will start to decompose and smell, but still one would not expect to catch a disease from it.

I would expect the urine output to tail off for a few hours due to the stress on the kidneys and the time it takes for the body to respond to the fluid.

the patients normal urine amount, because all you're doing is replacing fluid lost.
Rat urine looks like what anyone would expect urine to look like. It is a liquid, that can range in color or smell. The colors and smells are dependent on the rats diet.
Healthy urine consists of water, ammonia, potassium, hydrogen, little sodium, little creatine, little uric acid and urea and little bilirubin, if any of these substance is present in too much (or to little) quanity then it becomes unhealthy. Also if glucose and/or RBC are found in urine it is unhealthy.
The hanging wall of a normal fault would be expected to form the floor of a valley.
