We often refer to infrared radiation as being primarily heat (or thermal) radiation. But what exactly is heat, and how does it differ from temperature? Simply put, heat is a measurement of energy. All molecules contain some amount of kinetic energy, that is to say, they have some intrinsic motion. The hotter an object is, the faster the motion of the molecules inside it. Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance. When we say an object has a temperature of 100 degrees C, for example, we do not mean that every single molecule has that exact thermal energy. In any substance, molecules are moving with a range of energies, and interacting with each other as well, which changes their energies. But if we average the thermal energies of all the molecules together, we can obtain an object's temperature.

How many what best describes the relationship between heat and temperature?
Heat and temperature are related but distinct concepts. Heat is the transfer of thermal energy between two systems, while temperature is a measure of the average kinetic energy of the particles in a system. Increasing heat input to a system can raise its temperature, but other factors like the system's mass and specific heat capacity also play a role.
Which graph BEST represents the relationship between mass and inertia?
A scatter plot with mass on the x-axis and inertia on the y-axis is the best graph to represent the relationship between mass and inertia since it allows for visualizing any potential correlation or pattern between the two variables.
What Best describes the relationship between the velocity and pressure of a fluid?
The relationship between velocity and pressure in a fluid is described by Bernoulli's principle, which states that when the velocity of a fluid increases, the pressure decreases and vice versa. This relationship is based on the conservation of energy in a flow system.
Which best explains the relationship between evaporation and temperature?
Evaporation is the process in which a liquid changes into a gas, and it is influenced by temperature. Higher temperatures increase the kinetic energy of molecules in the liquid, allowing more molecules to escape into the gas phase, thus increasing the rate of evaporation. Conversely, lower temperatures slow down the evaporation process.
What statement best describes heat and temperature?
Heat and temperature are related but different concepts. Temperature is a measure of the average kinetic energy of particles in a substance, while heat is the transfer of energy between two substances due to a temperature difference. Temperature is the property of an object, while heat is the energy transferred between objects due to temperature differences.
How can you best describe the relationship between advertising and television?
Television is a medium driven by advertising and hence, profit.
Which word best describe the relationship between the lamb and the child in Williams Blake?
The word "innocent" best describes the relationship between the lamb and the child in William Blake's poem. It symbolizes purity, gentleness, and a sense of unity between the child and the lamb.

What statements best describe a conversion factor?
Given two variables n a linear relationship, the conversion factor between them is the gradient of their graph.
How is it best to describe the relationship between Juliet and her parents?
The relationship between Juliet and her parents isn't very good because they ask her to marry Paris without considering her feelings. They also claim she's dead to them when she refuses to marry Paris
Which graph best represents the relationship between air temperature and air density in the atmosphere?
The graph that best represents the relationship between air temperature and air density typically shows an inverse correlation. As air temperature increases, air density decreases due to the expansion of air molecules, which results in a lower mass of air per unit volume. Conversely, as temperature decreases, air density increases. This relationship is crucial for understanding atmospheric behavior and phenomena such as weather patterns and flight dynamics.
How can you best describe the relationship of a storys theme to its sublect or topic?
They are not the same
What is the relationship between luminosity and temperature for main sequence stars?
On such a diagram, those stars lie on a curve called the "main sequence". It is not a simple relationship - for example, it isn't a straight line on the diagram. Therefore, it isn't easy to describe in words. It's best if you look up "Main sequence", for example on the Wikipedia, and look at the corresponding diagram.
What best describe the relationship between a bill and a law?
a bill becomes a law once it is approved by both houses in the legislature, is proven constitutional, and is approved by the president
What is the BEST way to describe the relationship between Native Americans and Franciscan friars living on Georgia's barrier islands in the middle and late 1600s?
declining.
What best describe the temperature patterns Alaska?
cold all over
What term best describe the relationship between the halk and a field mouse?
The relationship between a hawk and a field mouse can best be described as predation. In this interaction, the hawk serves as a predator that hunts and feeds on the field mouse, which acts as its prey. This dynamic is a critical aspect of the food chain, illustrating the balance of ecosystems where predators and prey interact.
