Heating and Cooling Curves

Heating and Cooling Curves

When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance, q, and its...

Specific Heat

Specific Heat

The specific heat capacity of a substance refers to the energy required to increase the temperature of one gram of that substance by one degree Celcius. Specific heat capacity is often represented in calories (cal), grams (g), and degrees Celsius (oC), but can also be expressed in joules (J), kilograms (kg), and Kelvin (K), among other units.
For example, increasing the temperature of one gram of water by 1°C requires one calorie of heat energy and can be written as 1 cal/g-°C, or...

Quantifying Heat

Quantifying Heat

Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...

Heat Flow and Specific Heat

Heat Flow and Specific Heat

Heat is a type of energy transfer that is caused by a temperature difference, and it can change the temperature of an object. Since heat is a form of energy, its SI unit is the joule (J). Another common unit of energy often used for heat is the calorie (cal), which is defined as the energy needed to change the temperature of 1 g of water by 1 °C, specifically between 14.5 °C and 15.5 °C, since the energy needed shows a slight temperature dependence. Another commonly used unit is...

Heat Engines

Heat Engines

A heat engine is a device used to extract heat from a source and then convert it into mechanical work used for various applications. For example, a steam engine on an old-style train can produce the work needed for driving the train.
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...

Heat and Free Expansion

Heat and Free Expansion

The work done by a thermodynamic system depends not only on the initial and final states but also on the intermediate states—that is, on the path. Like work, when heat is added to a thermodynamic system, it undergoes a change of state, and the state attained depends on the path from the initial state to the final state. Consider an ideal gas cylinder fitted with a piston. When the cylinder is heated at a constant temperature, the gas molecules absorb energy and expand slowly in a...

Area of Science:

Occupational Health
Environmental Physiology
Wearable Technology

Background:

Construction workers in India face high risks of heat-related illnesses during summer.
Personal Cooling Garments (PCG) are microclimate devices designed to mitigate heat stress.
Understanding the efficacy of PCG in real-world worksite conditions is crucial.

Purpose of the Study:

To evaluate the applicability and physiological efficacy of wearing PCG for construction workers.
To assess the impact of PCG on subjective and physiological responses during field work.
To determine if PCG offers a viable solution for heat stress in occupational settings.

Main Methods:

A study was conducted on 29 healthy construction workers at actual worksites.
Participants' physiological responses were monitored while wearing PCG and habitual clothing (HC).
Climatic conditions included high temperatures (103.64 ± 38.3°F) and humidity (41.2 ± 13.4%).

Main Results:

Wearing PCG significantly lowered mean weighted skin temperature (38.66 ± 33.98°F vs. 32.36 ± 33.44°F with HC).
Mean sweat loss was significantly reduced when wearing PCG (0.365 ± 0.257 kg vs. 0.658 ± 0.342 kg with HC).
Heart rate and skin temperatures (back, chest) were also significantly reduced with PCG use.

Conclusions:

PCG effectively alleviates physiological strain and discomfort caused by environmental heat exposure.
PCG presents an affordable and practical method for protecting construction workers from heat stress.
The findings support the use of PCG as an assistive device in hot occupational environments.
