Heat is a form of energy that is transferred between objects in contact with each other or at different temperatures. There are three main mechanisms of heat transfer: conduction, convection, and radiation. Conduction requires physical contact, convection occurs through the motion of fluids, and radiation can occur through empty space. Temperature is a measure of the average kinetic energy of molecular motion and is measured using thermometers on standardized scales like Celsius and Kelvin. The amount of heat required to change the temperature of a substance depends on its specific heat. Architectural design can influence heat transfer through a building's envelope and systems.
Thermal energy is the total energy of all the atoms and molecules in a substance and is related to how fast those molecules are moving. Temperature is a measure of the average kinetic energy of molecules. Heat is the transfer of thermal energy between substances due to a temperature difference, which will continue until thermal equilibrium is reached where the substances have the same temperature. Specific heat capacity is a measure of how much thermal energy a substance needs to gain or lose in order to change its temperature by one degree.

The document discusses different types of symbiotic relationships that can exist within forest ecosystems. It defines parasitism as a relationship where one organism harms its host, commensalism as a relationship where one benefits without affecting the other, and mutualism as a relationship where both organisms benefit. Examples are given of each type, such as ticks being parasitic on deer, birds nesting in trees being commensal, and bees and flowers having a mutualistic relationship.
The document discusses different types of symbiotic relationships in nature. It provides examples of mutualism between species like crocodiles and birds, where the bird cleans the crocodile's teeth for food scraps. Hermit crabs have a symbiotic relationship with sea anemones, where the anemone protects the crab and gets leftover food. Buffalo allow oxpeckers to eat ticks off their skin in exchange for a warning signal of danger. Sharks carry remora fish, which eat parasites off the shark and get access to its leftovers. Lichen is a symbiotic partnership between fungi and algae that allows both to survive. The document also defines different types of symbiotic relationships like phoresis, comm
Symbiosis refers to two organisms living together where at least one benefits. There are three main types of symbiotic relationships: parasitism, where one benefits and one is harmed; mutualism, where both benefit; and commensalism, where one benefits and the other is unaffected. Examples provided include acacia plants with ant galls in a parasitic relationship and moray eels with cleaner fish in a mutualistic relationship.
Ecology is the study of interactions between living organisms and their environment. It involves studying both biotic factors like plants, animals, and microorganisms, as well as abiotic factors such as climate, geology, and nutrients. Ecology views each ecosystem as an integrated system of interdependent relationships between producers, consumers, and decomposers. Ecosystems can be studied at different levels of organization from the biosphere down to individual organisms. Ecology provides an integrated and dynamic understanding of the environment as a complex system with many interacting species.
The document provides information about the Pythagorean theorem:
1) It states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
2) It gives examples of right triangles that satisfy the theorem, such as ones with sides of 3, 4, 5 or 5, 12, 13.
3) It includes an animated proof of the theorem showing how the area of the square on the hypotenuse equals the combined areas of the squares on the other two sides.
The document discusses several key properties and theorems regarding circles:
1. Angles subtended by a chord in the same segment of a circle are equal. Similarly, angles subtended by an arc in the same segment are equal.
2. If two angles stand on the same chord of a circle, then the angle at the center is twice the size of the angle at the circumference.
3. The angle in a semi-circle is a right angle, where the angle stands on the diameter of the circle.
4. Opposite angles in a cyclic quadrilateral (a quadrilateral whose vertices all lie on the same circle) add up to 180 degrees.
This document defines key terms and concepts related to circles, including:
- A circle consists of all points equidistant from a fixed point called the center.
- The distance from the center to any point on the circle is called the radius.
- A line segment passing through the center whose endpoints lie on the circle is called the diameter. The diameter is twice the length of the radius.
- The length or distance around the entire circle is called the circumference. The circumference is approximately 3 times the diameter.
The document discusses the standard form of a circle equation and how to find the center and radius from the equation. It provides examples of writing the equation of a circle given the center and/or radius or a point on the circle. The standard form is (x - h)2 + (y - k)2 = r2, where (h, k) are the coordinates of the center and r is the radius. If the equation is not in standard form, it may need to be completed into a perfect square to extract the center and radius.
This document discusses key terms and measurements related to circles, including radius, diameter, and circumference. It defines radius as a line segment from the center to the edge, diameter as twice the radius, and circumference as the distance around the circle which can be estimated by multiplying the diameter by 3.
