Is Q zero in an isothermal process? For an isothermal reaction, the change will happen slowly enough to enable the system go back to the initial temperature by heat exchange(q), so q can never be zero in this process. Is an isothermal change an ideal gas obeys? In an isothermal change, an ideal gas obeys […]

What is Polar vs nonpolar?
What is Polar vs nonpolar? Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out. What is an example of a polar bond? Polar bonds are […]
What are biological and environmental factors?
What are biological and environmental factors? Biological factors such as breeding behavior, care of young, time of last eating, and food storage cause changes in daily activity patterns. Similarly, environmental factors such as temperature, snow cover, food supply and disturbance caused by humans in an urban setting also cause changes in daily activity patterns. What […]
Which side of the mountain receives the most precipitation?
Which side of the mountain receives the most precipitation? Much of airborne moisture falls as rain on the windward side of mountains. This often means that the land on the other side of the mountain (the leeward side) gets far less rain—an effect called a “rain shadow”—which often produces a desert. What causes more rain […]
What is a collapsing wave called?
What is a collapsing wave called? In fluid dynamics, a breaking wave or breaker is a wave whose amplitude reaches a critical level at which some process can suddenly start to occur that causes large amounts of wave energy to be transformed into turbulent kinetic energy. What is a fat wave? Fat waves occur when […]
What is sound of speech?
What is sound of speech? Speech sounds are also called phonemes. A phoneme is defined as the smallest part of spoken language that makes a difference in meaning. Remember that a phoneme is not the same as a letter! Phonemes are speech sounds. Letters are used to represent sounds. What are the different uses of […]
How many plant pigments are there?
How many plant pigments are there? three What are the four pigments found in chlorophyll? Chlorophyll a is the core pigment that absorbs sunlight for light dependent photosynthesis. Accessory pigments such as: cholorphyll b, carotenoids, xanthophylls and anthocyanins lend a hand to chlorophyll a molecules by absorbing a broader spectrum of light waves. How do […]
What are the 3 classifications of joints?
What are the 3 classifications of joints? Joints can be classified by the type of the tissue present (fibrous, cartilaginous or synovial), or by the degree of movement permitted (synarthrosis, amphiarthrosis or diarthrosis). What are the different kinds of joints? There are six types of freely movable diarthrosis (synovial) joints: Ball and socket joint. Permitting […]
