The correct answer is (c) Don’t leave your tap running while brushing your teeth, shaving, or washing the dishes. Fix leaky faucets and pipes right away.
As seen in the bar graph that huge amount of water is wasted in the domestic ways. By using the water in adequate amount and saving the water that is wasted while running the tap while brushing and fixing the leaks as soon as possible will save a huge amount of water. The bar graph is covering maximum wastage of water from these sections only. By reducing the water used in brushing, leaky faucets and others can save maximum water.
I’m pretty sure it’s A
Sorry if I get it wrong but I think it’s A for sure!
Exothermic reactions lose heat and are hot to the touch (Think explosion)
Endothermic reactions gain heat and are cold to the touch (Think of an instant ice pack where you pop it to make it cold)
The particulate nature of matter explains that when a substance gets heated it particles gets energised and they move away from one another in a random manner, hence the correct options are
- The space between the particles is different with more space between particles in a gas
- The particles will have different kinetic energy
<em>What happens to particles when they are heated</em>
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly
