Hi All I have a question regarding what type of chemical/solution that is recommended to dissolve solidified Copper(I) chloride around a ceramic coated sample. I know HCl and ammonia both works well with the copper(I) chloride). However, I don't want to damage the sample. I have tried EDTA...

Heat transfer problem--please help Homework Statement I have a heating mantle (180Watt) and i want to use it for heating a ceramics flask (thermal conductivity : 1.38 W/m*K), however, there is a stainless steel on top of the flask (at 10cm distance between the heating mantle and the...

WOW! thanks gokul! i ve been trying to find one but i cant! appriciate it! 1 more question though, for material density (especiall gas) at high temperature? do you know where i could find those? thanks!

Hi everyone, Please help me, I am almost dying for this project. I am doing a project that is dealing with high temperature, and i would like to ask you guys, is there any way to get the material properties of alloy, ceramics, or glass(fused quartz) at high temperature? i have tried to...

Hi, sorry to bring this question up again, i know it has been a long time, but i kind of have the same problem with this, could you please help me again? my question is, when i have a rigid closed system of water let's say in amount of 500mL and then i heat it up until 600C which is way pass...

directly proportional? k thanks redbelly! i think i got it! thnx

Yea i have tried both real gas and ideal gas equation and both of them almost the same, took me so long to find the van der waals constant+equation. Thanks Redbelly! and for both of calculation i used the density of argon at STP(1atm and 25C) which is 1.449kg/m3 is that okay? so it will be like...

Thnx redbelly98! ohhh so the volume stays the same? well :) i kno its a stupid question, its just that the volume tend to increase with the temperature right? And it is true right for Argon gas i can just use ideal gas equation, or should i go with the non-ideal gas formula? Thanks again!

Homework Statement Hi I am an Engineering student and i have to do an analysis on a closed system vessel that is going to be heated up.And before i start the experiment i want to an analysis or a safety factor for this experiment. I am going to have a closed system vessel, let's say the...
