Answer: The pressure at 273 K is 130 kPa.
Solution:- From Gay-Lussac's law, "At constant volume, the pressure of a given mass of a gas is directly proportional to the kelvin temperature."
The equation used for this is written as:
Where, is the pressure at
temperature and
is the pressure at
temperature.
Temperatures are already given in kelvin so no need to do the conversion. Let's plug in the values and calculate the new pressure.
On rearranging this for new pressure:
340/ 713 = p2/ 273
p2 = 340 x 273/ 713 = 130 kPa

Explanation:
When water is collected from vapour form to liquid form then this process is known as condensation.
For example, water evaporated from the atmosphere reaches to the clouds and it gets converted into liquid form and again reaches to Earth in the form of rain.
Thus, we can conclude that process in which water vapor turns to liquid is called condensation.
this process is called condensation. When it cant hold on much longer it will turn into rain or snow.

pure bleach b/c that is was helps destroy the bacteria
Final answer:
After transferring cultures with any equipment, it is best to immerse the equipment in pure bleach. Bleach is a strong disinfectant that can efficiently destroy various types of microorganisms.
Explanation:
After using loops, swabs, toothpicks, spreaders or any other equipment to transfer cultures, the equipment should ideally be immersed in pure bleach. This is because pure bleach effectively destroys many types of microorganisms found in these cultures. Pure bleach is a strong disinfectant that kills bacteria, viruses, and fungi, reducing the risk of spreading these organisms in the lab. Pouring bleach over the equipment can remove most of these organisms, but immersion guarantees thorough decontamination.
