What else can I help you with?
Gasoline engine convert chemical energy into kinetic energy. true or false?
A gasoline engine converts chemical energy into mechanical energy.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
True or false when a bond is broken in a chemical reaction heat energy is released?
It is true that when bonds are broken there is chemical reaction. Then heat energy is released.
Chemical energy is a type potential energy due to the composition of a substace True or false?
True. Chemical energy is a form of potential energy that is stored in the bonds between atoms and molecules in a substance. When these bonds are broken through chemical reactions, the stored energy is released.
True or false is chemical energy a type of potential energy due to the composition of a substance?
True. Chemical energy is a type of potential energy that is stored in the bonds between atoms within a substance. It is released during chemical reactions when these bonds are broken and new ones are formed.
Heterotrophs obtain the chemical energy used in metabolism from autotrophs or from other heterotrophs?
Heterotrophs are organisms that cannot produce their own food and must obtain their energy by consuming other organisms. They obtain chemical energy from the organic matter in autotrophs or other heterotrophs through processes such as ingestion and digestion. This energy is then used in their metabolic processes to fuel essential functions and activities.
In power plants generators convert mechanical energy into chemical energy?
false :)
Plants convert radiant energy from the sun into mechanical energy which is used to help them grow. true or false?
False. Plants convert radiant energy from the sun into chemical energy through the process of photosynthesis, not mechanical energy. This chemical energy is then used for various cellular processes, including growth.
Gasoline engine convert chemical energy into kinetic energy. true or false?
A gasoline engine converts chemical energy into mechanical energy.
Is this true or false in a chemical change other forms of energy cannot be changed to chemical energy?
False
True or false the reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are called the Calvin cycle?
False. The reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are part of the light-dependent reactions in photosynthesis. The Calvin cycle, on the other hand, is the series of reactions that occur in the stroma of chloroplasts and are responsible for carbon fixation and the production of sugars.
T or f heterotrophs can get the energy they need directly from the sun?
False. Heterotrophs cannot obtain energy directly from the sun; instead, they rely on consuming other organisms, such as plants or animals, to obtain their energy. Unlike autotrophs, which can produce their own energy through photosynthesis, heterotrophs depend on organic matter for sustenance.
True or false wind farms can directly convert wind into electricity?
Wind turbines convert wind energy to mechanical energy to electrical energy.
Is this true or false in a chemiccal change other forms of energy cannot be changed to chemical energy?
False. In a chemical change, other forms of energy, such as heat or light, can be changed into chemical energy. This transformation can occur during reactions where energy is either absorbed or released as chemical bonds are broken or formed.
All energy in the biosphere comes from the sun true or false?
True. The sun is the ultimate source of energy for nearly all life on Earth through the process of photosynthesis, where plants and other photosynthetic organisms convert sunlight into chemical energy.
True or false Solar energy is difficult to store?
Solar energy is impossible to store. Normally we try to use it straight away, or convert it into a storable form of energy such as chemical potential or electrical potential.
True or false activation energy is needed only by chemical reactions that release energy?
true activation energy is the minimum amount of energy needed to start a chemical reaction
