The equation to be used are:
PM = ρRT
PV = nRT
where
P is pressure, M is molar mass, ρ is density, R is universal gas constant (8.314 J/mol·K), T is absolute temperature, V is volume and n is number of moles
The density of air at 23.5°C, from literature, is 1.19035 kg/m³. Its molar mass is 0.029 kg/mol.
PM = ρRT
P(0.029 kg/mol) = (1.19035 kg/m³)(8.314 J/mol·K)(23.5+273 K)
P = 101,183.9 Pa
n = 0.576 g * 1 kg/1000 g * 1 mol/0.029 kg = 0.019862 mol
(101,183.9 Pa)V = (0.019862 mol)(8.314 J/mol·K)(23.5+273 K)
Solving for V,
V = 4.839×10⁻⁴ m³
Since 1 m³ = 1000 L
V = 4.839×10⁻⁴ m³ * 1000
V = 0.484 L
The temperature : 332.75 K
<h3>Further explanation</h3>
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
volume of gas = 790 cm³ = 0.79 L
mol of gas at STP :
Use ideal gas :
P=726 mmHg=0.955 atm
V= 1000 cm³ = 1 L
Hey there!
The independent variable is the factor that is deliberately manipulated in an experiment. The dependent variable is the variable in a relation whose value depends on the value of the independent variable.
Second, hypotheses and predictions are similar in that they are both related to an experiment. However, a hypothesis is an explanation for a phenomena that is testable through an experiment. A prediction is the expected result of an experiment.
An when conducting an experiment, it is always important to present accurate data even if that data does not support your hypothesis. If your data does not support the hypothesis, the experiment was not a waste of time. This data provides you with information regarding what is not happening in a particular phenomenon. Information gained from the experiment can help you to develop new hypotheses to test in the future.
Hope this helped.

In the solar cooker, reflective material like aluminum is used to collect and trap the heat from the sunlight while the interior is painted to reduce heat loss.
<h3>What is a solar cooker?</h3>
A solar cooker is a cooker which uses the energy of sunlight to cook food.
In designing a solar cooker, a solar collector such as reflective material like aluminum is used to collect and trap the heat from the sunlight.
The interior of the cooker is painted black to avoid heat loss by radiation.
Cardboard boxes are used as insulating materials.
In conclusion, a solar cooker is designed to maximize solar energy collected and minimize heat loss.
