If you’ve ever walked along a beach on a sunny day and dipped your toes in the water to cool them off after the hot sand,you’ve taken advantage of the specific heat of water. Despite how it may sound, specific heat doesn’t refer to the exact temperature of something. It’s a l...
The heat capacity and temperature are proportional to each other. On increasing the heat capacity of water, its temperature also increases. The...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer y...
Being able to find the the molar heat of a combustion candle is a necessary skill for passing basic chemistry. It centers around an experiment where a teacher has the student light a candle underneath a pail of water for a set period of time. Using the candle's change in mass, the wate...
Instead of grams, you need to convert into mol. This requires use of the molar heat capacity formula. That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/mol. molarheatcapacity=(4.18Jmol∗K)(18.0g1mol) Multiplying that toge...
Although they may have ventured into the water, they were terrestrial, or land-dwelling, animals. Their muscles and bones had several specific features. For example, all dinosaurs had cheek muscles that extended from their jaws to the tops of their skulls. Their hip girdles comprised three bones...
There are three essential elements involved in producing fire: heat, oxygen and fuel. To put a fire out, you need to effectively remove one of these elements. The best way to remove heat is to dump water on the fire. This cools the fuel to below the ignition point, interrupting the com...
Avoid opening the SIM tray of a wet iPhone. Doing so may let the ejected water get inside the iPhone, resulting in a damaged SIM card. Avoid using compressed air or an external heat source to accelerate the water evaporation. Heat can cause harm to the iPhone battery. Don’t put a wet...
As air loses heat, it also begins to lose its ability to retain moisture; the colder surface pulls and collects water from the warmer air, creating condensation. Your dehumidifier does pretty much the same thing. Most dehumidifiers can be broken down into five component parts: Fan Compressor -...
Leaving aside the considerations related to the selection of the materials (a choice that has though a direct influence on manufacturing costs), the problem is to find an “optimal” balance between the internal heat exchange coefficient in the channels and the related pressure loss. This is the...
To fill this gap, this study aims to explore ‘what is happening’ and ‘what is possible’ when pupils participate in multimodally designed teaching and create multimodal digital animations of water molecules and phase changes in water. Digital media have become increasingly prominent as “carriers...
