Subject: Which type of thermometer indicate a small rise in temperature faster?

I actually have 3 questions to ask on this. If 2 mercury thermometers are 
identical in every aspect except that one of the thermometer has a larger bulb 
than the other,(a)which one will give a larger range of temperature?For this, I 
am totally lost.(b)which one will indicate more quickly a small rise in 
temperature?Is it the one with a smaller bulb??(c)if the thermometers are 
replaced with alcohol filled thermometers, will answers in (a) and (b) be the 
same?I believe it may be the same? I would really like to know the reasons 
behind these questions.Please enlighten me on these. Hope to hear from you 
soon. Thank you.Have a nice day.
