Yes, a torch can be a source of both light and heat. The light is produced by the flame or the electric bulb, while the heat is generated by the burning fuel or the electric components.
A portable torch typically contains chemical potential energy stored in the batteries or fuel used to power the light source. When the torch is turned on, this energy is converted into light energy and heat energy.
When a torch is switched on, the electrical energy from the battery is converted to light energy and heat energy. The electrical energy powers the light source (such as LEDs or a bulb) to produce light, and a small portion of the energy is also dissipated as heat.
When using a torch, electrical energy is converted into thermal energy and light energy. The electrical energy is used to heat a filament inside the bulb, which then produces both heat and light.
Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.
Both light and heat are forms of energy that can be transmitted through space. They can both be emitted from a source and detected by the senses. Additionally, both light and heat can be absorbed, reflected, or transmitted by various materials.

We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.

When a torch is on, electrical energy is converted into light energy and heat energy. The electrical energy flows through the circuit of the torch, powering the light bulb to produce light and generating heat as a byproduct of the light production process.
light and heat
Water can be used to extinguish a running torch light as it cools down the heat source, breaking the chain reaction that produces the flame. Additionally, carbon dioxide or a fire extinguisher can also be used to put out a torch light by displacing the oxygen and suffocating the fire.
A torch produces light through a chemical reaction between the fuel source (such as propane, kerosene, or butane) and oxygen. When the fuel is ignited, it reacts with oxygen to produce heat and light. The light is the result of incandescence, where the high temperature of the reaction causes the fuel to glow and emit light.
