How do you calculate the heat capacity of water? The specific heat capacity of water is 4.18 J/g/°C. We wish to determine the value of Q – the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from […]
Is it possible to image insulators using STM?
Is it possible to image insulators using STM? Scanning tunneling microscopy is based on the flow of an electrical current and thus cannot be used to directly image insulating material. Hydrophilic insulators, such as glass and mica, can thus be imaged in humid air. What is the resolution of a TEM? Transmission Electron Microscope Resolution: […]
What does it mean when you dream of losing your purse?
What does it mean when you dream of losing your purse? Dreaming about losing your bag or wallet can represent loss of self-identity and control. If in your dream you leave your wallet or bag behind on purpose, it might symbolize you coming to terms with letting go of something that had significant meaning to […]
What is importance of design thinking?
What is importance of design thinking? Design thinking is a process for solving problems by prioritizing the consumer’s needs above all else. It relies on observing, with empathy, how people interact with their environments, and employs an iterative, hands-on approach to creating innovative solutions. What steps in design thinking would benefit you as a student […]
Is radon higher in summer or winter?
Is radon higher in summer or winter? To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have […]
What is impulse and its application?
What is impulse and its application? Impulse in Physics is a term that is used to describe or quantify the effect of force acting over time to change the momentum of an object. It is represented by the symbol J and usually expressed in Newton-seconds or kg m/s. What is difference between impulse and impulsive […]
Can arctic foxes be pets?
Can arctic foxes be pets? The arctic fox (Vulpes lagopus) is very similar to the red fox but is typically smaller and not as commonly kept as a pet. Due to a small breeding stock in the U.S., Arctic foxes are overbred and some possess genetic problems. Like red foxes, its urine and scenting glands […]
What are the three factors of sustainability?
What are the three factors of sustainability? The figure at the top of this page suggests that there are three pillars of sustainability – economic viability, environmental protection and social equity. What are the key principles of sustainability? The principles of sustainability are the foundations of what this concept represents. Therefore, sustainability is made up […]
What is the direction of electron current flow?
What is the direction of electron current flow? The flow of electrons is termed electron current. Electrons flow from the negative terminal to the positive. Conventional current or simply current, behaves as if positive charge carriers cause current flow. Conventional current flows from the positive terminal to the negative. How is electricity created by electrons? […]
Does higher pressure mean higher temperature?
Does higher pressure mean higher temperature? As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also increase. […]
