keep your thermostat set at a high temperature. So what temperature should you set your thermostat to during the winter? The Correct Winter Temperature for Your Thermostat Well, there really is no right or wrong answer to that question. However, most information regarding winter thermostat temperatures will tell you the ideal temperature for your thermostat during the winter is 60 to 65 degrees Fahrenheit. But most people feel more comfortable with the temperature set a little higher than that.…
hot object (high entropy) in a closed system because it would violate the expression: ∆S≥0 Entropy is a measure of the disorder in a system and it will always tend to stay the same or increase. When the temperature of an object increases, its entropy increases also, however when the temperature of an object decreases, the entropy decreases. The change in entropy is expressing using the equation: ∆S=Q/T where ∆S=change in entropy…
oversizing results in higher manufacturing and installation costs. The most appropriate metric to describe the performance of a heat exchanger is its thermal capacity, which is its ability to transfer heat between the hot and cold fluids at different temperatures. Thermal capacity depends on the design of the heat exchanger unit and the fluid properties that flow in the device. If the heat transfer surface is sufficient, the…
bromelain is started stable at 25% of enzyme concentration to 100% of enzyme concentration, pH 4 to 11, and the temperature range from 4oC to 37oC. For the concentration, it could happen because the presence of bromelain could break down the gelatin which makes the not solidified formation of the solution. In the temperature test, the lowest temperature makes the bromelain become optimum temperature which is regarded favorable for the digestive process, and on the pH level test was determine…
Quasi-S phase region When the temperature continues to cool down from 1058 °C, the ductility of the welds increases. To illustrate, ductility at 1053 °C is 0.00298, which is higher than the corresponding ductility at 1058 °C. At 1058 °C, Δε during welding is 0.00483. The expansion velocity and susceptibility of hot cracking decrease as (Δε-P) decreases. The increase in ductility is related to the microstructure of the welds at a temperature below 1058 °C. In this temperature range, the amount of…
also recombine into solid potassium nitrate. This reaction can reach a state where concentrations of ions remain constant or Ksp; which stands for the equilibrium concentration for the solubility product. The solubility of a compound changes with temperature, so Ksp changes too. Thermodynamics focuses on three large areas; which are enthalpy, entropy, and free energy. Enthalpy change or ΔH, for KNO3 dissolving…
the levels of physiological processes, despite changes in temperature. This experiment was coordinated to determine whether crayfish will show metabolic compensation when acclimated to various temperatures. The findings of this study show that temperature had no effect on crayfish oxygen consumption. The oxygen consumption for both the warm and cold acclimated crayfish was almost the same, despite the opposite direction of the temperature change. The results of this study therefore support the…
(MRMS) metabolic rate (oxygen consumption) for homeothermic endothermic female mice (Mus musculus) depending on their body mass and temperature of their environment. Mice were first weighed and then placed into 250mL chambers. The aquatic environments surrounding the chambers were acclimated to temperatures of 10°C, 15°C, 20°C, 25°C and 30°C. The effects of temperature and mass on metabolic rate of the female mice were measured by monitoring the oxygen consumption in a specific time interval,…
Hypothermia Did you know that hypothermia can come from a temperature as high as 60 degrees? Well it can, hypothermia is when the body temperature is 95 degrees or lower. There are two types of cases, normal, and severe. In normal the body temperature is in a range of 83 to 95 degrees. Severe hypothermia can be 82 degrees or lower. Basically the body temperature loses heat faster that you make heat. So, their are many symptoms, solutions, and causes that show, how to take care of hypothermia,…
For example, when the process is endothermic, the kinetic energy increases since the temperature increases, but remains constant at a phase change. However, during an exothermic process the kinetic energy decreases along with the temperature and during a phase change the energy and temperature will remain constant. The kinetic energy is opposite for each of the curves because as the kinetic energy decreases during the exothermic process…
