This is because on instruments, there might be harmful bacteria. These (as do any organism) function by having enzymes so catalyze critical reactions in a cell. When these enzymes (and all other proteins) reach a certain temperature, they are denatured (in other words, rendered useless). Without these enzymes, the bacteria dies and the instruments are now safe to use again (and won't infect anybody else).
Because they will kill bacteria
To sterilise the water.

Yes, olive oil can burn when used for cooking at high temperatures.
l am so sick to death of NO ONE ANSWERING THESE stupid questions
To clean snd sterilise the injection site
A thermocouple or a pyrometer would be used to measure a temperature of 900°C. These instruments are designed to withstand high temperatures and provide accurate temperature readings in such conditions.
Pyrometer
sa515 IS USED FOR INTERMEDIATE TO HIGH TEMPERATURES AND SA 516 IS USED FOR LOW TO MEDIUM TEMPERATURES.
A thermometer

No, a laboratory thermometer typically measures temperatures up to around 250-300°C. To measure the temperature of volcanic lava (600-1200°C), specialized high-temperature instruments such as infrared pyrometers or thermocouples are typically used.
