At a given pressure, gas particles with smaller masses move slower.
At a given temperature, gas particles with smaller masses move faster.
At a given temperature, gas particles with smaller masses move slower
Answer: Different gases effuse at different rates because at a given temperature, gas particles with smaller masses move faster.
Explanation: The motion of particles in a gas depends on the kinetic energy of the gas particles which further depend on the temperature of the gas. Thus, the rate of gas given by Graham's law can only be stated when the two gases are at fixed temperature.
Graham's Law: This law states that the rate of effusion of gas is inversely proportional to the square root of its mass.
Mathematically,
From the above relation, the gas particle with smaller mass will effuse faster at a given temperature.
Answer: it is easily magnetized
Explanation:
Answer:
Option A
Explanation:
Option A - Blue litmus paper turns red under acidic conditions so this option is correct.
Option B - Acids do not turn red litmus paper red, bases are the ones responsible for that. Hence, this option is incorrect.
Option C - Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion. This option is incorrect.
Option D - This option is incorrect as acid reacts with metal, to form salt and hydrogen.
Answer : The temperature on the kelvin scale is, 277.15 Kelvin
Explanation :
As we are given the temperature in degree Celsius. Now we have to need to convert the temperature from degree Celsius into kelvin.
Conversion used for the temperature from degree Celsius to Kelvin :
Therefore, the temperature on the kelvin scale is, 277.15 Kelvin
b. compound
c. solution
d. suspension
e. colloid
The substances that can't be separated into simpler substances or converted into other substances by chemical processes are elements. They are fundamental substances and cannot be changed into other elements through chemical processes. The correct answer to the given question is option a. elements
The answer to your question is a. elements. In chemistry, elements are substances that cannot be separated into simpler substances or converted into another substance by chemical processes.
This is what makes them fundamental substances. Chemical processes can change compounds, solutions, suspensions, and colloids into different substances, but they cannot change an element into a different element. For example, hydrogen is an element that cannot be converted into any other element through chemical processes. It is fundamentally hydrogen.
The correct answer to the given question is option a. elements
