Which conditions correspond to STP?Group of answer choices0 °C and 1 atm0 K and 760 torr25 °C and 1 bar

Break Down the Problem

1. Identify the standard conditions for temperature and pressure (STP).
2. Analyze each provided option to see if they meet the STP criteria.

Relevant Concepts

• Standard Temperature and Pressure (STP) is defined as:
  • Temperature: 0 °C (273.15 K)
  • Pressure: 1 atm (101.325 kPa)

Analysis and Detail

1. Option 1: 0 °C and 1 atm

   • This matches the definition of STP, as it corresponds to 273.15 K and 101.325 kPa.

2. Option 2: 0 K and 760 torr

   • 0 K is absolute zero and does not correspond to any standard condition. Moreover, 760 torr is equivalent to 1 atm, but the temperature is not acceptable.

3. Option 3: 25 °C and 1 bar

   • 25 °C (298.15 K) is warmer than the standard condition, and 1 bar is approximately equal to 0.9869 atm, which does not correspond to STP.

Verify and Summarize

• The only option that fits the definition of STP is the first one, which is at 0 °C and 1 atm.

Final Answer

The conditions that correspond to STP are 0 °C and 1 atm.
