Hot stimuli are detected by heat-sensitive receptors called thermoreceptors, while cold stimuli are detected by cold-sensitive receptors in the skin known as cold thermoreceptors. These receptors are specialized nerve endings that are able to detect changes in temperature and transmit this information to the brain to generate the sensation of heat or cold.
Skin can detect temperature changes, allowing us to feel hot or cold sensations. It also detects physical stimuli such as pressure, touch, and pain.
The 3 factors that determine the time and amount of change in a cell are the cell type, the specific stimuli acting on the cell, and the cell's intrinsic regulatory mechanisms. Cell type influences its responsiveness to stimuli, while the nature and strength of the stimuli dictate the magnitude of change. Intrinsic regulatory mechanisms such as feedback loops and signaling pathways modulate the speed and extent of cellular changes.

Conduction is the type of heat transfer that occurs when heat is transferred through a substance. In conduction, heat moves from higher to lower temperature regions within the substance.
Electrical , heat and chemical stimuli
Sensory neurons are responsible for relaying information about external stimuli such as heat to the brain. These specialized cells detect the stimulus and transmit signals to the central nervous system for processing and response.
Heat receptors detect thermal stimuli, such as higher temperatures above the baseline level. When activated, these receptors send signals to the brain, resulting in the perception of warmth or heat.
Chemoreceptors sense chemical stimuli. Mechanoreceptors sense mechanical stimuli. Thermoreceptors sense temperature stimuli. Photoreceptors sense light stimuli. Nociceptors sense pain stimuli.

If you mean "What is an organism's reaction to physical stimuli? it is usually withdrawal or avoidance. It depends on what type of stimuli and what type of organism. Is the organism used to this type of stimuli? Is it a new strange stimuli? The question is not specific enough to answer thoroughly nor is it grammatically correct.

An example of external stimuli is a loud noise that causes someone to cover their ears or flinch in response.
