When heat flows into a system, its value is positive, indicating an increase in the system's internal energy. Conversely, when heat flows out of a system, its value is negative, reflecting a decrease in the system's internal energy. This convention is used in thermodynamics to describe energy transfers.

The theory that states current flows from the most positive point to the most negative point is known as conventional current flow. This convention assumes that electric current consists of positive charge carriers moving from the positive terminal of a voltage source to the negative terminal. Although in reality, electrons (negative charge carriers) move in the opposite direction, conventional current flow remains a standard for electrical engineering and circuit analysis.
When a dry cell is connected in a series, the flow of electrons moves from the negative terminal to the positive terminal. Electrons are negatively charged particles and are attracted to the positive terminal while repelled by the negative terminal. This movement creates an electric current that flows through the circuit.
Volcanicity can have both positive and negative effects on humans. On the positive side, volcanic eruptions can create fertile soils, enhance mineral resources, and contribute to geothermal energy production. Conversely, the negative effects include the destruction of infrastructure, loss of life, and environmental hazards such as ash fallout, lava flows, and toxic gases, which can disrupt communities and ecosystems. Balancing these effects is crucial for sustainable development in volcanic regions.
No, the present value interest factor (PVIF) is not always negative; in fact, it is typically a positive value. The PVIF is calculated using the formula ( PVIF = \frac{1}{(1 + r)^n} ), where ( r ) is the interest rate and ( n ) is the number of periods. Since both ( (1 + r) ) and ( n ) are positive, the PVIF itself is also positive, representing the present value of future cash flows.
Heat is energy and cannot be negative, If you are talking about heat flow then if you define outflow to be negative then inflow is positive.

No, when heat flows into a system, it is considered positive. Positive heat indicates heat is being added to the system, increasing its internal energy. Negative sign would indicate heat is being lost or leaving the system.

Energy flows from the negative terminal to the positive terminal of a battery.
The current flows from negative to positive.
positive cash flows are inflows while negative cash flows means cash out flow from different activities.
There is no positive and negative conductor. There are just two ends of a conductor, namely positive and negative. It is usually said that electricity flows from the positive to the negative side of a conductor, but scientists have discovered, that current consists of electrons that always flows from the negative to the positive side.
Current flows form negative to positive. I know this may seem odd considering the the negative is ground, but that is how it flows.
The type of current that flows from positive to negative is called conventional current. This convention was established before the discovery of electrons and defines current as the flow of positive charge. In reality, electrons, which carry a negative charge, move from the negative terminal to the positive terminal, but conventional current still represents the flow of positive charge in circuits.
