Soil has a specific heat capacity of 1.700J/g C. During the day, the temperature of soil in a
flowerpot increased from 15.6°C to 35.5°C. If the energy from the sun was calculated to be 251 175J,
what was the mass of the soil? Show your work.
Answers
Answer:
m = 7.42 kg
Explanation:
Given that,
The specific heat of the soil, c = 1.700J/g C
The temperature of soil in a flowerpot increased from 15.6°C to 35.5°C.
The energy released from the Sun is 251175 J. We need to find the mass of the soil.
We know that,
[tex]Q=mc\Delta T\\\\or\\\\m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{251175}{1.7\times (35.5-15.6)}\\\\m=7424.62\ g[/tex]
or
m = 7.42 kg
So, the mass of the soil is equal to 7.42 kg.

1. The total pressure of a gas mixture is 1.05 atm. The mixture contains 55% carbon dioxide, 31% nitrogen, and 14% hydrogen.
What is the partial pressure of the carbon dioxide in the mixture?
Answers
Answer:
0.15
Explanation:
The partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.
What is Dalton's law?Dalton's law can be described as the total pressure of all gases exerted being equal to the sum of the partial pressures of every gas in the mixture of non-reacting gases.
The total pressure of a gas mixture of gases can mathematically be defined as :
P (total) = P₁ + P₂ + P₃ + ......
Given, the total pressure of a gas mixture = Ptotal = 1.05 atm
The fraction of carbon dioxide in the mixture = 55 % = 0.55
The fraction of nitrogen in the mixture = 31 % = 0.31
The partial pressure of carbon dioxide in the mixture can be calculated as:
P(CO₂) = 0.55× P(total)
P(CO₂) = 0.55× 1.05
P(CO₂) = 0.58 atm
Therefore, the partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.

Right after Javier constructed the sling psychrometer, both thermometers had the same reading. Do you predict that the thermometers will still show the same temperature after Javier swings the psychrometer in a circle for a minute?
Answers
Answer:
No, they will not have the same temperature.
Explanation:
No, they will not have the same temperature.
What is Thermometer?An instrument that measures temperature is a thermometer. It is able to gauge the temperature of solids like food, liquids like water, and gases like air.
Celsius, Fahrenheit, and kelvin are the three most popular temperature measuring units. The metric system includes the Celsius scale. The metric system of measuring also contains units for length (like kilometres) and mass (like kilograms).
Nearly all nations in the world use the metric system as their official unit of measurement, which includes Celsius. The Celsius scale is used to measure temperature in most scientific disciplines.
Therefore, No, they will not have the same temperature.

Explanation:
Harold’s car has a fuel efficiency of 35 miles per gallon. Frank’s car has a fuel efficiency of 12 kilometers per liter. Who gets better gas milage, Harold or Frank?
Answers
Answer: Harold car has better mileage
Explanation: US gallon is 3.785 litres and one mile is 1.6 km.
35 · 1.6 km/ 3.785 l = 14.8 km/l
The Harold's car has a fuel efficiency of 35 miles per gallon and has better gas mileage.
What is efficiency?The efficiency is defined as the peak level of performance that uses the least amount inputs to achieve the highest amount of output.
Effectiveness is the ability to produce a better result, one that delivers more value or achieves a better outcome.
Efficiency is expressed as
Efficiency = output / input
The mileage of Harold's can be calculated as:
US gallon has 3.785 liters and 1 mile is 1.6 km
Thus mileage = 35 x 1.6 km / 3.785 l
= 14.8 km/l
Mileage of Frank's car = 12 x 1.6 km / 3.785 l
= 5.07 km/l
Thus, the Harold's car has a fuel efficiency of 35 miles per gallon and has better gas mileage.
