Answer:
Weather is the condition of Earth’s atmosphere at a particular time and place, whereas climate is the characteristic weather in an area over a long period of time.
Explanation:
Weather and climate are two very important conditions that describes the atmospheric overview of a place.
Weather is reported over a short period of time, it is the condition of the atmosphere at a particular time and place.
Climate is reported over a long period of term. The average weather condition of a place over a long period of time is the climate.
- The most important control over the climate of a place is the temperature and amount of precipitation it receives over a period of time.
- Weather conditions is reported using more diverse factors such a temperature, pressure, humidity, precipitation, etc.
Answer: We need true value to find out who is more accurate.
Explanation:
Precision refers to the closeness of two or more measurements to each other.
Accuracy refers to the closeness of a measured value to a standard or known value.
For Example: If you weigh a given substance five times and you get 3.0 kg each time. Then the measurement is very precise.
For Example: If the mass of a substance is 3.0 kg and one person weighed 3.05 kg and another person weighed 3.2 kg. Then, the weight measured by first person is more accurate.
According to the question:
Density measured by Mary = 2.226 g
/ml
Density measured by Joseph= 2.335 g
/ml
As, the standard or known value is not given, we can not know which student’s value is more accurate
We can apply Charles's law:
V/T = constant
V₁/T₁ = V₂/T₂
V₂ = 3 x 200 / 300
V₂ = 2 L
Description: The standard enthalpy of reaction is the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.
