The melting of ice is an endothermic change. what best describes the temperature conditions that are likely to make this a spontaneous change?

any temperature, because entropy increases during melting.
any temperature, because entropy decreases during melting.
low temperature only, because entropy decreases during melting.
high temperature only, because entropy increases during melting.

D

Explanation:

Entropy is the measurement of disorder. The warmer the temperature the more the disorder. As ice melts it goes from low disorder to much higher disorder.

The question is not exactly clear. What I just wrote is closest to D so use that as your answer, but it is very poorly worded. Higher temperatures will increase the entropy but only once the ice has melted. I cannot suggest what else you might try if D is wrong.

i'm pretty sure its b i might be wrong though!

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
