“How can I describe and
compare objects and materials based on odor and taste?
Answers
Answer:
There are several ways to describe and compare materials based on odor and taste. This includes adjectives that describe the object/materials,
Explanation:
You can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.
How many types of objects are there based on taste?There are five types of objects or materials that are based on the attribute of taste. This is because of taste receptors in the mouth sense the five taste modalities. It incudes sweetness, sourness, saltiness, bitterness, and savoriness (also known as savory or umami).
Scientists have classified odors into 10 basic categories: fragrant, woody/resinous, minty/peppermint, sweet, chemical, popcorn, lemon, fruity (non-citrus), pungent and decayed.
Both taste and odor of the materials and objects are represented with the help of a part of speech known as adjectives. Adjectives can be used to describe the qualities of someone or something independently or in comparison to something else, such as taste, color, odor, etc.
Therefore, you can definitely describe and compare objects and materials based on odor and taste with the help of adjectives.

Radio waves and the are various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. They are important because Radio waves are very widely used in modern technology for fixed and mobile radio communication, broadcasting, radar and radio navigation systems, communications satellites, wireless computer networks and many other applications.
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication. They are important because microwaves play an increasingly wide role in heating and cooking food. They are absorbed by water and fat in foodstuffs (e.g., in the tissue of meats) and produce heat from the inside. In most cases, this reduces the cooking time a hundredfold.

compare the approximate distance from Hawaii and approximate age of the mountains in the Hawaiian–Emperor Seamount Chain. In your graph, be sure to include data from the seven mountains.
Answers
Explanation:
I don't have the data specific for this question, but I do have a general understanding of the science behind this and what the shape of this graph should look like.
The underwater mountain range and the Hawaiian Island chain were formed by a mantle plume hot spot, which is a hotter area in the mantle. Magma from the boundary between the lower mantle and inner core floated up due to its higher temperature and cooled to become a rock after reaching earth's surface, forming and island or volcano.
However, due to the movement of the Pacific Plate, this volcano moved away from its place precisely over the hot spot. Without heat from underneath, these volcanoes could no longer be active, rendering them extinct. The hot spot continued spewing lava, forming another volcano and repeating the cycle.
Over time, the rock from these volcanoes weathered and eroded away, causing them to sink under sea level and forming the mountain range and island chain.
Knowing the backstory behind Hawaii's formation, we can conclude that the islands further away from Hawaii, the biggest island with active volcanoes, are older in age.

write down everything that you know about heat temperature pressure and heat transfer
Answers
Answer:
Heat is always transferred from the object at the higher temperature to the object with the lower temperature. For a gas, the heat transfer is related to a change in temperature. The temperature, pressure, and volume of the gas determine the state of the gas. Heating a gas changes the state of the gas.
Explanation:
This is something I know about heat temperature pressure and heat transfer
The object with the higher temperature always transfers heat to the thing with the lower temperature. The heat transfer for gas is connected to a temperature change.
What is meant by heat transfer?Heat transfer is defined by thermodynamic systems as "The transfer of heat over the system boundary caused by a temperature difference between the system and its surroundings."There are several ways for heat to go from one place to another. The many heat transmission mechanisms consist of:Conduction: Thermal energy is transferred from an area with higher kinetic energy to an area with lower kinetic energy. Slow-moving particles gain kinetic energy as a result of collisions between high-speed and slow-moving particles. This common type of heat transmission occurs when two objects physically touch. Convection: The flow of fluid molecules from higher temperature regions to lower temperature regions is referred to as convection.Radiation: Radiant heat is the name for thermal radiations. Emission of electromagnetic waves results in the production of thermal radiation. The energy from the producing body is removed by these waves. A vacuum or transparent media, which can be made of solid or liquid, is used for radiation transmission.To learn more about heat transfer, refer to:

Answer:
The element that has the highest combined number of protons and neutrons is Oxygen: 16 amu
Explanation:
The atomic mass unit (amu) of an element is the sum of the number of protons and neutrons in the atom of that element.
The atomic mass unit of the element reveals the total number of protons and neutrons in the element.
Since oxygen (16 a.m.u) has the highest atomic mass unit among the given elements in this question, therefore, it has the highest combined number of protons and neutrons.
