In the field of chemistry, standard temperature and pressure (STP) conditions are typically defined to ensure consistency in experimental conditions. According to these definitions:

1. Temperature:
- The standard temperature is 273 K. This is equivalent to 0°C.

2. Pressure:
- The standard pressure is 1 atm (atmospheric pressure).

Given these criteria, we analyze the provided options:

- [tex]$-273^{\circ} C$[/tex]: This is not correct. The standard temperature is 0°C or 273 K.
- [tex]$273 K$[/tex]: This is correct. The standard temperature is indeed 273 K.
- [tex]$760 cm^3 (Hg)$[/tex]: This is not a standard unit of pressure for STP in chemistry. The correct pressure is noted as 1 atm.
- [tex]$0K$[/tex]: This is not correct. 0 K is absolute zero, not the standard temperature for STP.
- [tex]$1 atm$[/tex]: This is correct. The standard pressure is indeed 1 atm.

Thus, the correct answers are:

- [tex]$273 K$[/tex]
- [tex]$1 atm$[/tex]
