What is the expected behavior?

What went wrong?
I have notice in Task manager that, I have open 4 tab in single chrome browser but in task manager it has shows 10 instance of Chrome .exe as shown in attached file and all 10 instance use the memory. So that If user open more tabs or run multiple application in chrome, memory might get increase and that cause to hang chrome browser and system.I have also notice that if chrome browser is in idle stat then also memory increases continuously. 

Did this work before? No 

Chrome version: 57.0.2987.133  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: 

If user working on chrome browser with 4 tab is open and in that case if chrome get crashed accidentally. In that case chrome might still be running in background and that might be reason showing more exe in task manager
