What is latent heat and its types? Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling). What is Latent Heat explain with example? Latent heat, energy absorbed or […]
What are the four basic principles of germ theory?
What are the four basic principles of germ theory? The four basic principles of Germ Theory The air contains living microorganisms. Microbes can be killed by heating them. Microbes in the air cause decay. Microbes are not evenly distributed in the air. What is Pasteur’s germ theory? In 1861, Pasteur published his germ theory which […]
Why is the pulley less than 100% efficient?
Why is the pulley less than 100% efficient? It is important to remember that NO pulley system is 100% efficient. This is due to friction of the ropes against the pulley wheels and the friction of the bearings of the pulley wheels as they rotate. This type of pulley arrangement will always have the same […]
Why does my child struggle with transitions?
Why does my child struggle with transitions? Sensory processing challenges Although sensory processing is not a diagnostic term like ADHD or autism, kids with either disorder-or no disorder-can have sensory processing issues, which can lead to problems with transitions. For kids who are easily over stimulated, the world feels confusing and seems to move too […]
What are 3 ways sediment can move to a new location?
What are 3 ways sediment can move to a new location? Sediment moves from one place to another through the process of erosion. Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, […]

What does a hollow point do to a body?
What does a hollow point do to a body? But what does this have to do with hollow points? Well, it’s simple. Since a hollow-point bullet expands when it enters soft tissue, it creates a larger wound channel inside the target, increasing the chances that incapacitating damage will be done. Can you survive a hollow […]
What are the four properties of water?
What are the four properties of water? The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. What are physical and chemical properties of water? We have seen the physical and chemical properties of water and understood its […]
Which physical quantity among the following remains on change when sound wave is reflected from a plane surface?
Which physical quantity among the following remains on change when sound wave is reflected from a plane surface? frequency Which is the following is the requirement for regular reflection of sound? Sound must come back to the person after 0.1 second. For above condition, the reflecting surface must be at a minimum distance of 17.2m. […]
Which gas is the main cause of greenhouse effect?
Which gas is the main cause of greenhouse effect? Carbon Dioxide Why oxygen is not a greenhouse gas? Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. These are symmetric molecules, made of two identical […]
