exothermic heat is negative
A different opinion:
Heat itself cannot be negative. An exothermic reaction is a chemical reaction wherein a substance gives up heat. Since the substance is giving up energy in the form of heat, the enthalpy change of the substance is negative.
Wasted thermal energy is typically dissipated into the surrounding environment as heat. This can contribute to an increase in the overall temperature of the surrounding area, which is known as thermal pollution and can have negative impacts on the environment. Reducing wasted thermal energy through energy efficiency measures can help minimize these negative effects.
The lattice energy of a compound is always negative.
The work done on a system is positive when energy is added to the system, and negative when energy is removed from the system.
No, the lattice energy can be positive, negative, or zero, depending on the specific compounds involved.
In energy sources, the positive symbol usually represents energy being supplied or generated, while the negative symbol represents energy being consumed or lost. Positive energy indicates a net input or gain, while negative energy indicates a net output or loss.
positive to a negative
Energy flows from the negative terminal to the positive terminal of a battery.
depends if your talking about positive and negative energy the answer would be: yes it does it has positive energy in it

Thermal energy can have several positive impacts, such as providing efficient heating for homes and industries, facilitating power generation through steam turbines, and enabling various industrial processes. However, its negative impacts include environmental concerns, such as increased greenhouse gas emissions from fossil fuel combustion and the potential for thermal pollution in bodies of water, which can harm aquatic ecosystems. Additionally, excessive heat can lead to health risks and contribute to climate change. Balancing these effects is crucial for sustainable energy management.
Whether you mean lighting or lightning, the energy is positive.
positive and negative charges
No, the lattice energy can be positive, negative, or zero, depending on the specific compounds involved.
No, the free energy of a cell reaction is negative when the emf of the cell reaction is positive. This is because a positive emf indicates that the reaction is spontaneous and capable of performing work, resulting in a negative change in free energy.
In energy sources, the positive symbol usually represents energy being supplied or generated, while the negative symbol represents energy being consumed or lost. Positive energy indicates a net input or gain, while negative energy indicates a net output or loss.
