Which form of energy moves spontaneously from hot objects to cold objects?
Heat energy moves spontaneously from hot objects to cold objects through a process called heat transfer. This transfer occurs until both objects reach thermal equilibrium, where they have the same temperature.
Does the movement of molecules to fill the room require energy?
No, the movement of molecules to fill a room does not require additional energy beyond the thermal energy that drives their random motion. This process, called diffusion, occurs spontaneously as molecules move from regions of higher concentration to regions of lower concentration until the concentration is uniform throughout the room.
Why doesn't osmosis require energy?
The reason it doesn't require energy is because the water is just flowing with the concentration gradient. it doesn't need energy for the same reason there is wind. the air is working to the concentration of the air.
What is the transfer of thermal energy from a warmer object to a cooler object called?
The transfer of thermal energy from a warmer object to a cooler object is called heat transfer. This process occurs spontaneously to achieve thermal equilibrium between the two objects.
Is it true or false that transfer of thermal energy by radiation does not require matter?
True. Transfer of thermal energy by radiation does not require matter because it occurs through electromagnetic waves, such as infrared radiation, which can travel through vacuum where there is no matter. This form of energy transfer is how heat from the sun reaches Earth.
What is the movement of molecules from areas high concentration to areas of low concentration?
Diffusion.
What is the movement of solutes from one area to another?
The movement of solutes from an area of high concentration to an area of low concentration is called diffusion. This process occurs spontaneously and does not require energy input.
Which energy change occurs in an operating voltaic cell?
Chemical energy is spontaneously converted to electrical energy.
What term describes the increase in energy expenditure that occurs in a person who fractures a leg?
Adaptive thermogenesis
What is the meaning of the passive transport?
The inter-membranous transport occurs in two ways: 1) Active Transport: occurs against the concentration gradient, Expenditure of energy occurs. 2) Passive transport: Refers to phenomena wherein transfer occurs along the concentration gradient i.e. from high concentration to low concentration, without any expenditure of energy.

Why is no energy required in passive transport processes?
In passive transport processes, no energy is required because molecules move across the cell membrane from an area of high concentration to an area of low concentration, following the natural flow of diffusion. This movement occurs spontaneously and does not require the cell to expend energy.

Heat energy moves spontaneously from hot objects to cold objects through a process called heat transfer. This transfer occurs until both objects reach thermal equilibrium, where they have the same temperature.

How does the amount of cellular energy used to move a molecule into a cell by active transport compare to the energy used for its movement by passive diffusion?
Active transport requires a significant amount of cellular energy, typically in the form of ATP, to move molecules against their concentration gradient, whereas passive diffusion relies on the natural kinetic energy of molecules and does not require energy input. In essence, active transport is energy-intensive because it actively pumps substances into the cell, while passive diffusion occurs spontaneously and is driven by concentration differences. Consequently, the energy expenditure for active transport is much higher than that for passive diffusion.
Why doesn't osmosis require energy?
The reason it doesn't require energy is because the water is just flowing with the concentration gradient. it doesn't need energy for the same reason there is wind. the air is working to the concentration of the air.
Coupling occurs when the energy released by an exergonic reaction is?
captured and used to drive an endergonic reaction. This allows the energy released by one reaction to be harnessed and used to power a different reaction that would not occur spontaneously. Coupling reactions are essential for many biological processes that require energy input.
