What are the laws of thermodynamics?

The laws of thermodynamics are generalized principles dealing with energy and heat.

What is the Zeroth Law of Thermodynamics?

The zeroth law of thermodynamics states that two objects in thermodynamic equilibrium with a third object are also in equilibrium with each other. Being in thermodynamic equilibrium basically means that different objects are at the same temperature.

What is the First Law of Thermodynamics?

The first law deals with conservation of energy. It states that neither mass nor energy can be destroyed; only converted from one form to another.

What is the Second Law of Thermodynamics?

The second law states that the entropy (the amount of energy in a system that is no longer available for work or the amount of disorder in a system) of an isolated system can only increase. The second law also states that heat is not transferred from a lower-temperature system to a higher-temperature one unless additional work is done.

What is the Third Law of Thermodynamics?

What is Mass?

Mass is a measure of the amount of substance in an object.

What is Weight?

Weight is a measure of the gravitational pull of Earth on an object.

What is Volume?

Volume is a measure of the amount of space occupied. There are many formulas to determine volume. For example, the volume of a cube is the length of one side cubed (a^3) and the volume of a rectangular prism is length times width times height (l \times w \times h). The volume of an irregular shape can be determined by how much water it displaces.

What is Density?

Density is a measure of the amount of mass per unit volume. The formula to find density is mass divided by volume (D = m/V). It is expressed in terms of mass per cubic unit (e.g., grams per cubic centimeter g/cm^3).

What is Specific Gravity?

Specific gravity is a measure of the ratio of a substance

’s density compared to the density of water.

What is Pitch?

Pitch is the quality of sound determined by frequency. For example, a musical note can be tuned to a specific frequency. A, for instance, has a frequency of 440 Hz, which is a higher frequency than middle C. Humans can detect frequencies between about 20 Hz to 20,000 Hz.

What is Loudness?

Loudness is a human’s perception of sound intensity.

What is Sound intensity?

Sound intensity is measured as the sound power per unit area and can be expressed in decibels.

What is Timbre?

Timbre is a human’s perception of the type or quality of sound.

What is Oscillation?

Oscillation is a measurement, usually of time, against a basic value, equilibrium, or rest point.

What are Elements?

Elements are substances that consist of only one type of atom.

What are Compounds?

Compounds are substances containing two or more elements. Compounds are formed by chemical reactions and frequently have different properties than the original elements. Compounds are decomposed by a chemical reaction rather than separated by a physical one.

What are Solutions?

Solutions are homogeneous mixtures composed of two or more substances that have become one.

What are Mixtures?

Mixtures contain two or more substances that are combined but have not reacted chemically with each other. Mixtures can be separated using physical methods, while compounds cannot.

What is Heat?

Heat is the transfer of energy from a body or system as a result of thermal contact. Heat consists of random motion and the vibration of atoms, molecules, and ions. The higher the temperature is, the greater the atomic or molecular motion will be.

What is Energy?

Energy is the capacity to do work.

What is Work?

Work is the quantity of energy transferred by one system to another due to changes in a system that is the result of external forces, or macroscopic variables. Another way to put this is that work is the amount of energy that must be transferred to overcome a force. Lifting an object in the air is an example of work. The opposing force that must be overcome is gravity. Work is measured in joules (J). The rate at which work is performed is known as power.

What is Thermal energy?

Thermal energy is the energy present in a system due to temperature.
