How is this an improvement on the traditional, paper coffee filters? a: they are less wasteful and more cost effective because they last longer b: a permanent filter is more expensive than a traditional filter c: they contain plastic which does not break down as easily as paper d: the coffee brewed using permanent filters does not taste as good?
it is titanium(lll). that's the answer.
answer; ///(u-235); ///is the correct
a because kcl 2 and k + cl cancel out and both of the ca cancel each other out
here we have to explain the use of the energy release by water to form ice in electrical ice-maker
the energy is conserved in the ice in the from of bond energy.
there remain hydrogen bonds in the liquid state of water but on addition of electrical energy in ice-maker the state of water changes from liquid to solid. in this change the volume of the water decreases and the hydrogen bond present in water become more stronger.
the potential energy released by the water is consumed in its ice form as hydrogen bond energy.
on addition of electric energy to form ice from water, the energy is used to form stronger hydrogen bond.
