How do you increase surface area? The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. How can you increase the surface area of water? Surface tension is the energy […]
What is the best form of power?
Does higher pressure mean more flow?
Does higher pressure mean more flow? Flow rate is the effect. Higher pressure causes increased flow rate. If the flow rate increases, it is caused by increased pressure. What is the relation between speed and flow rate? Flow rate and velocity are related by \(Q=A\overline{v}\\\) where A is the cross-sectional area of the flow and\(\overline{v}\\\) […]
Why does temperature increase with mass?
Why does temperature increase with mass? If density increases ,volume decreases and if density decreases , volume increases. So density*volume=mass remains same as before. Gravitational pressure increases the more mass there is, and that pressure creates energy that increases temperature. Why does it take longer to heat up a larger volume of water? Simple: you’re […]
Is 50 hp enough for a motorcycle?
What type circuit connection should a light bulb be connected to maintain maximum brightness?
What type circuit connection should a light bulb be connected to maintain maximum brightness? Answer. Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go […]
Is nitrogen harmful to humans?
Is nitrogen harmful to humans? High concentrations of nitrogen gas can be particularly harmful to human health. Nitrogen can displace oxygen from ambient air within an enclosed space leading to a dangerous build-up of the inert gas. Is nitrogen safe to consume? Liquid nitrogen, although non-toxic, can cause severe damage to skin and internal organs […]
What are the types of radio stations?
What are the types of radio stations? Different types of radio Conventional FM: As previously mentioned, conventional FM is a popular technology in analog radio. MPT1327: Perhaps the most widely used analog trunking technology today is called MPT 1327. Tetra: As the world becomes more digital, a number of digital radio technologies have emerged. Who […]
How are the two variables associated with each other?
How are the two variables associated with each other? Association between two variables means the values of one variable relate in some way to the values of the other. Association is usually measured by correlation for two continuous variables and by cross tabulation and a Chi-square test for two categorical variables. What can be used […]
What is one effect of the uneven heating of Earth caused by the sun?
What is one effect of the uneven heating of Earth caused by the sun? Usually when we talk about uneven heating of the Earth’s surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and […]
