Endothermic

Human beings (endothermic homeotherms) maintain their core body temperature around 37°C (98.6° F) by homeostasis in response to changes in the surrounding temperatures and do so through conduction, convection, radiation and evaporation. The hypothalamus of the brain, kidneys and liver are the organs that help control homeostasis and it is thermoregulation that plays a vital role in homeostasis for the stability of our body temperature. Homeostasis, keeping the balance: An important role in…

To do this, endothermic animal must obtain a substantial amount of food daily for heat production (Altringham, 1996). Bats that live in high latitudes go into torpor during the winter when the temperature falls and when food become scarce. Torpor is characterized by reduction…

Chloroplast are found in plants, they are responsible for the metabolism of energy to produce food for plants by breaking down Carbon dioxide, water and sunlight through a process called Photosynthesis. Once Carbon Dioxide enters a plant through stomata pores in a plant, water is absorbed through the roots of a plant and sunlight captured by chlorophyll pigments inside the chloroplast which is actually inside the thylakoids. It 's the russian doll complex., it is within the chloroplast that…

Energy profile of exothermic reaction Energy profile of endothermic reaction A)Doc Brown (2016) B)Doc Brown (2016) Thermodynamic reactions occur when there is a difference of energy during a chemical reaction. There are two types; Firstly, Exothermic reactions; This is when the initial reactants use less energy to break their existing bonds, than what energy was required to make the new bonds. The extra heat is spreads out into the surroundings (see above diagram A) An…

of different liquids, to conclude the role of the molecular size and structure of the intermolecular forces. Part A: In the first part of the experiment, the temperature changes will by measuring by the liquids evaporation, and since it is an endothermic reaction, the temperature will decrease. The temperature probes will be connected, and the computer will prepare to collect the data, as a first step. Two…

However, now with the endothermic and exothermic reactions, chemical energy exchanges showcased through this technology can save a municipality millions each year. Deep water cooling is a sustainable resource due to water's unique properties. Water, which does not freeze in large…

Chemical Reactions I Purpose The purpose of this experiment was to test and see how four different chemical reaction worked. The four different chemical reactions are formation, decomposition, single-replacement, and double-replacement. The hypothesis of this experiment was that in each of the different reactions something would happen to the reactant whether it be color, mass, temperature, or pressure. II Equipment For this experiment Late Nite lab was used. In Late Nite Lab the equipment…

can be categorized based on the release or absorption of energy. For instance, chemical reactions that release energy are known as exothermic reactions and have a positive change in enthalpy. Moreover, chemical reactions that absorb energy are endothermic, which have a negative change in enthalpy. Since the energy released is usually heat, keeping track of the heat flow in reactions will help determine the change in enthalpy of a reaction. Observing the measurement of heat changes is known as…

color change, gas formation, temperature change, precipitate formation, odor, and change in acidity. In the hot and cold pack experiment we found it to be a chemical reaction An exothermic reaction is when the substance releases heat energy. An endothermic reaction is when the substance absorbs heat energy. In our experiment we created a cold pack. We indicated that the reaction for this experiment would be exothermic. We think this because exothermic is releasing the heat which would make it…

Based on the results I got, the smaller the animal was the lower the mean LDH activity was. Another factor that can affect the LDH levels in a species could be where the animals live. Lizard-fish, which had the highest mean LDH activity, tend to live in shallow and deep waters all around. They like to burry themselves in sand or mud on the bottom and not move until prey comes along. My group’s hypothesis was incorrect, croaker fish did not have the highest LDH activity. Lizard-fish and croaker’s…
