What else can I help you with?
Which state of matter has the least molecular motion?
The solid state has the least molecular motion.
What molecular changes happen when thermal energy is added or removed from nitrogen?
When thermal energy is added to nitrogen, the molecular motion increases, causing the molecules to vibrate and move more rapidly. This results in an increase in temperature. When thermal energy is removed, molecular motion decreases, leading to a decrease in temperature. The phase of nitrogen may change depending on the temperature, transitioning between solid, liquid, and gas states.
Molecular motion in a gas is the minimum possible at?
The molecular motion in a gas is at its minimum possible at absolute zero temperature. At this temperature, the molecules have almost zero kinetic energy, causing them to come to a stop and exhibit minimal motion.
Which term describes the describes the disorder of random molecular motion?
entropy
What is the temperature at which all atomic and molecular kinetic motion ceases?
The temperature is absolute zero, a minimum temperature of matter based on continually reduced molecular motion. (Although absolute zero cannot be attained, it is possible to get very very close, to about 170 billionths of a kelvin.) Absolute zero is approximately -273.15 °C
Air temperature is a measure of the?
a measure of molecular motion
How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level
What is a measure of the average of motion of molecular?
The measure of the average motion of molecules is temperature. Temperature is a reflection of the average kinetic energy of the molecules in a substance.
How molecular motion changes as a substance changes from one state to another?
As a substance changes from a solid to a liquid, the molecular motion increases as the intermolecular bonds break and the molecules can move past each other more freely. When a substance transitions from a liquid to a gas, the molecular motion increases further as the molecules have enough energy to overcome intermolecular forces entirely and move independently.
How do the molecular energy molecular motion and overall mass of a substance change when matter changes state?
When matter changes state, the molecular energy generally increases as heat is added or decreases as heat is removed. Molecular motion increases as the substance transitions from a solid to a liquid to a gas. The overall mass of the substance remains the same throughout the phase change process, as no particles are added or removed.
What is a measure of the motion of particles?
One measure of the motion of particles is velocity, which is the speed and direction of the particles. Another measure is acceleration, which describes how the velocity of the particles changes over time.
How do you measure and graph changes in motion?
To measure changes in motion, you can use tools like a speedometer, accelerometer, or motion sensors. To graph these changes, plot time on the x-axis and the measured variable (e.g., speed or acceleration) on the y-axis. This can help visualize the motion patterns over time.
Is the measure of the amount of resistance an object has to changes in its state of motion?
Resistance to changes in its state of motion is measured by inertia, which is the tendency of an object to maintain its velocity. The larger the mass of an object, the greater the inertia and resistance to changes in motion.
What are two examples of changes in state that will generate an increase in molecular motion?
Melting ice to form liquid water or boiling liquid water to produce steam are two examples of changes in state that lead to an increase in molecular motion. In both cases, the added energy causes the molecules to move more rapidly and with greater freedom.
When measure hot or cold something is you measure its?
When measuring how hot or cold something is, you measure its temperature using a thermometer. Temperature is a measure of the average kinetic energy of the particles in a substance - higher temperature means more kinetic energy and increased molecular motion, resulting in what we perceive as hot, while lower temperature means less kinetic energy and decreased molecular motion, resulting in what we perceive as cold.
WHICH observation does not show molecular motion?
Observation of an object at rest or stationary would not show molecular motion.
What happens to the molecular motion when heat energy is increased?
When heat energy is increased, the molecules in a substance gain more kinetic energy and move faster. This increased molecular motion leads to a rise in temperature and can result in changes in the state of matter, such as melting or boiling.
