Which substance supplies us with the energy needed to sustain normal daily activity?
Carbohydrates are the main source of energy for the body, providing fuel for daily activities. When broken down, carbohydrates are converted into glucose, which is used by the cells as energy.
What is the substance that supplies energy to fuel cell activity?
The substance that supplies energy to fuel cell activity is typically hydrogen. It is used as the fuel source in the anode compartment of the fuel cell and undergoes a reaction that produces electrons and protons, which then generate electricity.
What element is that is necessary for a substance to burn?
Oxygen is necessary for a substance to burn. It reacts with the substance in a chemical reaction known as combustion, releasing heat and light energy. Without oxygen, the substance will not be able to sustain a fire.
What chemical directly supplies your muscles with energy?
Adenosine triphosphate (ATP) is the chemical that directly supplies energy to muscles during physical activity. ATP is generated from the breakdown of carbohydrates, fats, and proteins in the body through a process called cellular respiration.
Does thermal energy depend on amount of substance?
Yes, thermal energy does depend on the amount of substance. The more mass a substance has, the more thermal energy it can store. This is because thermal energy is related to the internal energy of a substance, which increases with the amount of substance present.

What is a form of energy caused by increased molecular activity and is a measure of the total energy of the substance?
The form of energy caused by increased molecular activity is called thermal energy. It is a measure of the total kinetic and potential energy of the molecules in a substance due to their motion and vibration. Thermal energy determines the temperature of a substance.
What is the energy barrier and how does it relate to the concept of ignition temperature?
The energy barrier is the minimum amount of energy required for a chemical reaction to occur. Ignition temperature is the minimum temperature at which a substance will ignite and sustain combustion. The energy barrier must be overcome for the substance to reach its ignition temperature and undergo combustion.
What element is that is necessary for a substance to burn?
Oxygen is necessary for a substance to burn. It reacts with the substance in a chemical reaction known as combustion, releasing heat and light energy. Without oxygen, the substance will not be able to sustain a fire.
Is a chain reaction possible in a substance that emit no neutrons when it fission?
No, a chain reaction is not possible in a substance that emits no neutrons when it undergoes fission. Neutrons are required to sustain a chain reaction by triggering the fission of other atoms in the substance. Without neutron production, the fission process cannot continue to release energy and sustain the chain reaction.
What are two definitions of energy?
In physics, energy is the capacity to do work. It can exist in various forms such as kinetic, potential, thermal, and chemical energy. In a broader sense, energy refers to the internal strength or vitality required to sustain physical or mental activity.
What will happen to the state of the substance the atomic or molecular activity and the shape of the graph when thermal energy is added?
When thermal energy is added to a substance, the atomic or molecular activity will increase, leading to higher kinetic energy of the particles. This results in the substance changing states from solid to liquid, and then to gas, if the temperature continues to rise. The shape of the graph will show an increase in temperature with corresponding changes in state, known as phase transitions.
If the length of an activity is greater than 150 seconds the energy system is predominantly used?
If the length of an activity exceeds 150 seconds, the aerobic energy system becomes the predominant source of energy. This system relies on oxygen to convert carbohydrates and fats into energy, supporting sustained physical activity. In contrast, shorter bursts of activity primarily utilize the anaerobic energy systems, which do not require oxygen but can only sustain energy production for limited durations. Thus, for prolonged activities, the aerobic system is essential for maintaining performance.
Predict what will happen to the state of the substance the atomi and molicular activity?
As the substance undergoes an increase in temperature, its atomic and molecular activity will also increase. This will result in the particles moving faster and having more energy, potentially leading to a change in state if the substance reaches its melting or boiling point.
What chemical directly supplies your muscles with energy?
Adenosine triphosphate (ATP) is the chemical that directly supplies energy to muscles during physical activity. ATP is generated from the breakdown of carbohydrates, fats, and proteins in the body through a process called cellular respiration.
What kind of energy do you use to climb a rope?
When you climb a rope, you primarily use muscular energy from your arms, shoulders, and back to pull yourself up. Your body also relies on cardiovascular energy to sustain the physical exertion and maintain endurance throughout the activity.
